UGC NET Paper 2: Library & Information Science 2nd January 2026 Shift 1 (Previous Year Paper)

The correct answer is D, B, A, E, C

Key Points

• D. Defining the research problem – The process begins by clearly identifying the issue or problem to be studied.
• B. Conducting a literature review – Existing studies are reviewed to understand background knowledge and research gaps.
• A. Formulation of testable hypotheses – Hypotheses are developed based on gaps identified in the literature.
• E. Collecting high-quality data – Data is collected according to the research design formulated after the hypothesis.
• C. Preparing and presenting the research report – Findings are analyzed, interpreted, and reported with conclusions and recommendations.

Additional Information

• The scientific research process is a systematic and evidence-based approach used to generate new knowledge.
• It begins with observation and identification of a research question or problem.
• Background research (literature review) is conducted to understand existing knowledge.
• A testable hypothesis is formulated based on the research problem.
• An experiment or research design is planned, and data is collected systematically.
• The collected data is analyzed and interpreted to draw valid conclusions.
• The findings are communicated through reports, publications, or presentations.
• The process is continuous and cyclical, often leading to new questions and further research.

The correct answer is Both A and R are true, but R is not the correct explanation of A.

Key Points

• Assertion A is true because Academic Social Networking (ASN) sites such as ResearchGate, Academia.edu, and Mendeley are specifically designed to support scholarly communication.
• They allow researchers to share publications, exchange ideas, build academic profiles, and collaborate with peers across institutions and countries, thereby strengthening academic communities at both national and global levels.
• Reason R is also true, as ASN platforms can indirectly enhance research opportunities by providing access to information on funding calls, collaborations, and research networks.
• Increased visibility and networking may help researchers connect with potential funding agencies or project partners.
• However, Reason R does not correctly explain Assertion A because the primary reason ASN sites promote scholarly communication is their collaborative and knowledge-sharing features, not their role in enhancing research funding opportunities.
• Funding support is a secondary benefit and not the core function explaining scholarly communication.

Therefore, both statements are correct, but R is not the correct explanation of A.

The correct answer is A-II, B-III, C-I, D-IV

Note: The Original Question was dropped from the final answer key, so we have made few changes in the options.

The correct answer is Limited flexibility in combining new concepts

Key Points

• In pre-coordinate indexing, concepts are combined at the time of indexing in a fixed citation order decided by the indexer.
• Once this order is set, the user must search using the same structure.
• This makes the system rigid and less flexible when new or unexpected combinations of concepts are needed.

Additional Information

• High cognitive load on the user during retrieval
• This is more typical of post-coordinate systems, where users must combine terms themselves during searching.
• Lack of need for controlled vocabulary
• Pre-coordinate systems require a controlled vocabulary to maintain consistency.
• Unsuitability for printed indexes 
• Pre-coordinate indexing is actually well-suited for printed indexes (e.g., classified catalogues, subject heading lists).

​Pre-coordinate indexing

• Pre-coordinate indexing systems are designed to precisely describe the content of documents by using combinations or coordination of component terms.
• These systems aim to create subject headings that represent compound concepts, and the entries are arranged in classes based on the subject content of the document.
• Pre-coordinate indexing involves coordinating or combining ideas and terms at the time of preparing an index.
• Examples Include:
• ​​Chain procedure,
• PRECIS,
• COMPASS
• POPSI, etc.

Post- coordinate Indexing-

• The indexing system which has the ability to freely coordinate terms at the time of the search, providing an unlimited number of access points to a document belongs to the post-coordinate or coordinate indexing models.
• Post-coordinate indexing system was first conceived by Mortimer Taube in 1953 as a means of organizing the research reports acquired by the US Armed Services Technical Information Agency.
• The most important feature of the post-coordinate indexing system is that "No sequence of terms or citation order is necessary".
• For example-  Uniterm Indexing.

The correct answer is applying periodic format migration and emulation approaches.

Key Points

• Technological obsolescence is a major risk in digital preservation because hardware, software, and file formats evolve quickly.
• Format migration ensures long-term access by converting digital files into current, stable formats or moving them to newer systems.
• Emulation recreates obsolete environments in modern systems, allowing access to digital objects in their original form, preserving functionality and user experience.
• Regular use of these active preservation strategies is essential; passive storage alone cannot address ongoing technological change.

Additional Information

• Strict copyright checks before ingest: These address legal compliance, not technological obsolescence.
• Multiple redundant backups without migration: Backups prevent data loss but do not ensure usability when formats or platforms become obsolete.
• Restricting access to only the latest versions: This risks losing original content, context, and functionality, undermining true preservation.

Important Points

Implementing a Digital Preservation Strategy

• While digital preservation strategies vary in approach, their implementation follows a similar process (National Archives of Australia, 2007):
• Identify Records for Preservation: Select digital materials that require preservation.
• Choose an Appropriate Strategy: Determine the preservation method (emulation, migration, encapsulation) and the necessary technologies. For example, emulation may require software to recreate the original environment; migration needs compatible applications to convert formats; encapsulation involves packaging records with metadata.
• Test the Solution: Conduct thorough testing on duplicate records to ensure the process works without affecting the originals.
• Backup Source Records: Create verified backups of all records before applying any preservation treatment. These serve as master copies if the chosen approach fails.
• Apply Preservation Treatment: Implement the chosen strategy. Migration and encapsulation modify the record’s format, while emulation preserves the record in a new environment without alteration.
• Verify Integrity: Audit preserved records to ensure no loss or structural changes and update metadata to reflect the preservation treatment.
• Dispose of Originals if Appropriate: Once verified, duplicate source records may be safely destroyed.
• Monitor Records: Regularly check the integrity, functionality, and metadata of preserved records to maintain stability and identify future preservation needs.

The correct answer is Balancing Open Access with users' sensitive data

Key Points

• Dissemination is about making information accessible. The ethical tension arises because:
• Openness is a scholarly and social good (knowledge should be free, transparent, and widely available).
• Privacy and sensitivity are moral obligations (protecting individuals, communities, or organizations from harm).
• This creates a conflict of values:
• If you prioritize Open Access, you risk exposing sensitive or confidential data.
• If you prioritize privacy, you may restrict access and limit knowledge sharing.
• That tension—two equally valid but conflicting principles—is the hallmark of an ethical dilemma.

Additional Information

• The information life cycle typically includes:
• Creation/Collection – Data is generated or gathered.
• Organization/Processing – Data is classified, indexed, and structured.
• Storage/Preservation – Decisions about formats, repositories, and long-term curation.
• Dissemination/Access – Information is shared, published, or distributed to users.
• Use/Reuse – Information is applied in research, decision-making, or practice.

The correct answer is C, B, A, E, D

Key Points

• Chain indexing is a cost-effective method of facilitating access to terms without duplicating the hierarchical arrangement of the classification within the alphabetical index.
• Ranganathan initially introduced the concept of chain indexing in his 1938 book, "Theory of Library Catalogue."
• Chain indexing was used in the British National Bibliography (BNB) in the 1950s and 1960s until it was replaced by PRECIS-indexing.
• According to Ranganathan, chain indexing is a
• “procedure for deriving class index entry (i.e. subject index entry) which refers from a class to its class number in a more or less mechanical way.'
• Chain indexing involves several steps to derive different types of subject headings:
• Construct the Class Number: Classify the subject of the document using a preferred classification scheme, creating a class number based on the scheme's notation.
• Represent Class Number in Chain Form: Express the class number as a chain, with each link comprising the class number and its verbal translation in standard terms or phrases from the chosen classification scheme.
• Determine Links: Identify various types of links, including Sought Links (SL), Unsought Links (USL), False Links (FL), and Missing Links (ML).
• Prepare Specific Subject Heading: Derive specific subject headings by starting from the last sought link and working upwards, using a reverse rendering process. If the subject contains space, time, or form isolates, split the chain accordingly and derive subject headings from each part in reverse order, arranging components based on their derivation sequence.
• Prepare Subject Reference Headings: Create subject reference headings from each upper sought link, exhausting all terms from the upper sought links during indexing.
• Prepare Subject Reference Entries: Generate subject reference entries or 'see also' references from each subject reference heading to its specific subject heading. If a subject heading begins with a space, time, or form isolate, use 'See' references instead of 'See also' references.
• Prepare Cross References: Create cross-references ('see' references) for alternative and synonymous terms or headings found in specific and subject reference headings.
• Alphabetize Entries: Merge specific subject entries, subject references, and cross-references, arranging them alphabetically into a single sequence

The correct answer is Clifford Lynch.

Key Points

• UNESCO (2003) classifies digital preservation strategies into four main categories:
• Short-term Strategies
• Medium- to Long-term Strategies
• Investment Strategies
• Alternative Strategies

Medium- to Long-term Digital Preservation Strategies:

• These strategies aim to ensure long-term access to digital information despite continuous technological changes.
• Migration
• Migration refers to transferring digital data from one hardware, software, or format to another without altering its intellectual content.
• It helps preserve the integrity, usability, and accessibility of digital objects over time.
• Migration may involve shifting data between computer systems or converting files from obsolete formats to newer ones.
• Example: Moving files from an HP-based system to a SUN-based system or converting outdated image formats.
• Canonicalization
• Canonicalization involves converting digital objects into a standard or canonical form that captures their essential characteristics.
• It helps verify that no significant information is lost during format conversion.
• Different digital formats (especially images) can be mapped to a common canonical format.
• This method ensures integrity and authenticity independent of specific storage formats.
• The concept of canonicalization was first introduced by Clifford Lynch (1999).
• Emulation
• Emulation preserves digital objects by recreating the original hardware and software environment in a newer system.
• It maintains the original “look and feel” and functionality of digital resources.
• Emulation removes the need to preserve outdated hardware.
• It works through emulator programs that translate instructions between old and new computing environments.
• In some cases, emulation is more cost-effective than migrating large digital collections.
• Intellectual Property Rights (IPR) issues may arise, requiring trusted organizations for implementation.

Key Points

• ASCII:​
• The acronym ASCII represents the American Standard Code for Information Interchange, which serves as a method for character encoding in text documents on computing systems and communication devices.
• In 1963, the American National Standards Institute introduced the ASCII (American Standard Code for Information Interchange) standard, outlining a seven-bit pattern for computer representation of letters, numbers, symbols, and control signals.
• Originally derived from telegraphic codes, ASCII's initial use was for a seven-bit teleprinter code promoted by Bell Data Services.
• The American Standards Association's X3.2 subcommittee commenced work on ASCII on October 6, 1960.
• Its first edition was published in 1963, followed by a significant revision in 1967, and the latest update in 1986.
• ​EBCDIC:​
• EBCDIC (Extended Binary Coded Decimal Interchange Code) is an eight-bit character encoding primarily used on IBM mainframe and midrange computer systems.
• It evolved from the code originally used with punched cards and the six-bit binary-coded decimal code used with many of IBM's computer peripherals in the late 1950s and early 1960s.
• EBCDIC was introduced in 1963-1964.
• It was designed to expand upon the Binary-Coded Decimal (BCD) Interchange Code (BCDIC), which was initially developed to efficiently encode zone and numeric punches on punched cards using six bits.
• UTF-EBCDIC is a character encoding designed to encode the full range of 1,112,064 valid Unicode character code points using one to five one-byte (8-bit) code units, unlike UTF-8 which uses a maximum of four.
• Extended ASCII:
• Extended ASCII was introduced by IBM in 1981 with the launch of its first Personal Computer (PC).
• It expanded the original 7-bit ASCII standard by using 8 bits, allowing for 256 characters to support additional symbols, graphics, and European languages.
• Although several 8-bit character sets had been developed in the late 1970s by companies such as HP, the IBM PC popularized Extended ASCII and made it a de facto industry standard.
• Over time, multiple variants—known as code pages (such as IBM Code Page 437) and standards like ISO 8859—emerged to support different languages and regional requirements.
• ISCII:
• ISCII (Indian Script Code for Information Interchange) is a character encoding standard that enables the representation of multiple Indian languages within a single framework.
• ISCII (Indian Script Code for Information Interchange), created in 1988, was introduced in 1991 by the Bureau of Indian Standards (BIS). ISCII uses an 8-bit encoding scheme with a total of 256 characters.
• The first 128 characters (0–127) are identical to ASCII, while the remaining 128 positions (128–255) are used to represent characters from various Indian scripts.
• Since most Indian scripts are derived from the ancient Brahmi script and share similar phonetic structures, a common encoding system was feasible.
• This design enables easy transliteration between different Indian writing systems.
• UNICODE:
• Unicode, managed by the Unicode Consortium, is an encoding standard supporting text from all major writing systems globally.
• Its latest version, 15.1, encompasses 149,813 characters and 161 scripts, covering various contexts, including literary, academic, and technical domains.
• Unified within the standard are numerous common characters, numerals, punctuation marks, symbols, and over thousands of emojis.
• This coding scheme was introduced in 1991.
• It uses variable bit encoding according to the requirement. For example, UTF-8, UTF-16, UTF-32

The correct answer is Expectancy, Instrumentality, Valence

Key Points Expectancy Theory (VIE Theory):

• Vroom’s Theory of Expectancy:
• ​​Vroom's Expectancy Theory of motivation posits that an individual's motivation is influenced by their expectations regarding the future
• According to this theory, motivation is shaped by three key factors:
• Expectancy: This aspect revolves around the belief that increased effort leads to improved performance. In other words, the conviction that working harder results in better outcomes
• Instrumentality: Here, the belief is that good performance leads to valuable outcomes for the individual. It signifies that if one performs well, there are positive incentives.
• Valence: Valence refers to the importance an individual places on the expected outcome. For instance, someone motivated by financial rewards may not value additional time off. It reflects the significance attached to the anticipated outcome.

The correct answer is A, C, D only.

Key PointsCharacteristics Of Qualitative Inquiry:

• Qualitative research focuses on the study of complex human and social problems in totality, unlike the scientific method of concentrating on the study of fragmented variables or situations or events.
• In qualitative research, the human and subjective approach is highlighted.
• The studies are conducted in a natural/actual setting i.e., to observe the events without making any manipulations or controls on variables studied.
• It involves a variety of data gathering techniques and approaches of qualitative nature viz., case study, interviews, dialogues, observations, personal experience, life story, visual data like photography, etc.
• Qualitative researchers are concerned primarily with the process, rather than outcomes or products.
• The process of qualitative research is inductive in that the researcher builds abstractions, concepts, hypotheses, and theories from details.
• Qualitative research is descriptive in that the researcher is interested in the process, meaning, and understanding gained through words or pictures.
• The qualitative researcher is the primary instrument for data collection and analysis. Data are mediated through this human instrument, rather than through inventories, questionnaires, or machines.

Additional Information

1. Experimental research helps in establishing causal relationships among different variables in a situation under controlled conditions. Experimental research is undertaken when a researcher wishes to trace cause-and-effect relationships between defined variables.
   2. Generalisation, which is an act of reasoning that involves drawing broad inferences from particular observations, is widely acknowledged as a quality standard in quantitative research but is more controversial in qualitative research. The goal of most qualitative studies is not to generalize but rather to provide a rich, contextualized understanding of some aspect of human experience through the intensive study of particular cases.

The correct answer is Both A and R are correct and R is the correct explanation of A.

Key Points

• Assertion A: Taxonomies provide higher semantic precision than folksonomies: True
• Taxonomies are structured classification systems with clearly defined relationships and controlled vocabularies.
• They offer semantic precision because terms are curated, standardized, and hierarchically organized.
• Folksonomies, on the other hand, are user-generated tags (like hashtags or keywords) that lack formal structure, leading to ambiguity and inconsistency.
• Reason R: They are developed through formal term governance and strict hierarchical relationships: True
• Taxonomies are built using formal governance, meaning experts define terms, relationships, and rules.
• They often follow strict hierarchies (e.g., broader term → narrower term), which enhances clarity and precision.
• Relationship Between A and R:
• R explains why taxonomies are more semantically precise than folksonomies.
• The formal governance and hierarchy are the very reasons taxonomies outperform folksonomies in precision

• However, authenticity alone is not enough. A source must also be accurate—meaning the information it contains must be factually correct and reliable.
• Example: A genuine letter from a historical figure may still contain incorrect claims or biased views.
• Reason R: External criticism is, therefore, referred to as lower criticism of the data.
• External criticism (also called lower criticism) is the process of verifying the authenticity of a document—checking its origin, authorship, date, and physical integrity.
• It contrasts with internal criticism (or higher criticism), which evaluates the accuracy, meaning, and reliability of the content.
• Relationship Between A and R:
• R explains A directly:
• Since authenticity is necessary but not sufficient, historians begin with external criticism to establish authenticity.
• This is why external criticism is called lower criticism—it’s the foundational step before assessing accuracy.

Additional Information

• Experimental method:
• A systematic scientific approach used to establish cause-and-effect relationships in research.
• It involves manipulating one or more independent variables to observe their effect on dependent variables.
• The method is conducted under controlled conditions to isolate the effect of the independent variable.
• Independent Variable (IV): The variable deliberately changed by the researcher.
• Dependent Variable (DV): The variable measured to assess the effect of the IV.
• Ex-post facto research:
• Ex-post facto research is a quasi-experimental method in which the researcher studies relationships after events have already occurred.
• In this method, the independent variable is not manipulated because it is either impossible or unethical to do so.
• It is also called “after-the-fact” research as the investigation starts after the occurrence of the event.
• The method relies on retrospective analysis of existing data to identify possible cause-and-effect relationships.
• Random assignment is not used, and participants are studied in naturally formed or intact groups.
• Groups are compared based on pre-existing conditions (e.g., smokers vs. non-smokers).
• Ex-post facto research is causal-comparative in nature, seeking to explain why and how differences occurred.
• It is commonly used in social sciences where controlled experimentation is not feasible.
• Descriptive Survey Method:
• Descriptive Survey Method is a non-experimental research method used to describe the present status of a population, situation, or phenomenon.
• It focuses on what exists at the time of study without manipulating any variables.
• The main purpose is to collect, analyze, and interpret data related to characteristics, opinions, attitudes, or behaviors.
• Common data collection tools include questionnaires, interviews, schedules, and observations.
• The method answers questions like what, where, when, and how, but not why.
• Data collected may be quantitative (percentages, frequencies, statistics) or qualitative (descriptive information).\
• The researcher studies phenomena in their natural setting without control or experimentation.
• Types of descriptive surveys include census surveys, sample surveys, cross-sectional surveys, and longitudinal surveys.
• This method is widely used in education, social sciences, and public opinion studies.
• ​Ethnographic Method:
• ​Ethnographic Method is a qualitative research approach used to study the culture, behavior, and social life of a group in its natural setting.
• It originated in anthropology and emphasizes first-hand, in-depth understanding of a community.

• Participant observation is the main technique, where the researcher observes while actively participating in daily activities.
• Data is collected through field notes, interviews, recordings, and document analysis.
• The method is flexible, allowing changes in research focus as new themes emerge.
• It emphasizes the emic (insider’s) perspective of participants.
• Reflexivity is important, requiring the researcher to be aware of personal bias and influence on the study.

The correct answer is Both A and R are correct and R is the correct explanation of A.

Key Points

• Assertion A: "During the network communication, when an attacker is 'Eavesdropping', it is referred to as sniffing or snooping. This kind of eavesdropping is the biggest security problem that administrators face while managing the network."
• This is correct
• Eavesdropping in networking refers to intercepting data packets as they travel across the network.
• It’s also called sniffing or snooping, especially when tools like Wireshark or tcpdump are used.
• It’s a major concern because attackers can capture sensitive data like passwords, emails, or financial information.
• Reason R: "'Eavesdropping' can be avoided by using strong encryption services that are based on Cryptography."
• This is Correct
• Encryption ensures that even if data is intercepted, it cannot be read without the decryption key.
• Cryptographic protocols like SSL/TLS, IPSec, and HTTPS protect data in transit.
• So yes, cryptography is the key defense against eavesdropping.
• Relationship Between A and R: R explains A perfectly:
• Eavesdropping is a serious threat (A), and
• Cryptography-based encryption is the solution (R).
• This is a cause-effect relationship: the problem (eavesdropping) is mitigated by the solution (encryption).

The correct answer is 9 volumes

The Correct answer is Misleading, Ugly, Superseded, Trivial, Irrelevant, Elsewhere available.

Key Points

• MUSTIE is the acronym for six negative factors that make books and other materials prime candidates for weeding.
• A few of these factors are noted as not relevant for ebooks but most can be applied to them. 
• Misleading (and/or factually inaccurate).
• Weed outdated editions and books that are no longer accurate. Pay special attention to areas where information has changed recently or where it changes rapidly, like in medicine and travel.
• Ugly: Not relevant to e-books.
• Superseded (by a truly new edition or by a much better book on the subject).
• ​Especially for reference materials, test guides, and travel manuals, weed older editions. Most public libraries don’t need to keep older editions for research value
• Trivial (of no discernible literary or scientific merit; usually of ephemeral interest at some time in the past).
• Weed older titles that were of fleeting interest or are about outdated popular culture.
• Irrelevant to the needs and interests of your community.
• ​Even e-books should be expected to circulate or be used online at least once every few years.
• Also weed self-published e-books that are not circulating.
• Elsewhere – the material is easily obtainable from another library

Additional Information

• General guidelines for collection management are adapted from the CREW method.

• Replacement checking and ordering
• Set up displays for low circulating, high quality books that would benefit from exposure.
• CREW manual was created by the Texas State Library and Archives Commission.

The correct answer is A, C only.

Key Points

• Central Tendency – Mean: Correct
• Central tendency refers to the center or typical value in a dataset.
• The mean (average) is one of the three main measures of central tendency, along with the median and the mode.
• So this pairing is accurate and textbook-aligned.
• Regression Curve – Hypothesis: Incorrect
• A regression curve is a statistical tool used to model the relationship between variables (e.g., predicting Y from X).
• A hypothesis is a statement or assumption tested through research.
• While regression analysis may be used to test hypotheses, the curve itself is not a hypothesis—it’s a result or model derived from data.
• So this pairing confuses a method with a conceptual statement.
• Refinement of Judgement – Delphi Method: Correct
• The Delphi method is a structured communication technique used to gather expert opinions.
• It involves multiple rounds of questioning, with feedback provided after each round, allowing experts to refine their judgments.
• This method is widely used in forecasting, policy analysis, and strategic planning.
• D. Absolute Zero Point – Likert Scale: Incorrect
• A Likert scale is ordinal, meaning it ranks responses (e.g., strongly agree to strongly disagree).
• It does not have an absolute zero point, which is a feature of ratio scales (like weight, height, income).
• An absolute zero means “none” of the quantity exists—Likert scales don’t measure quantities in that way.
• E. Descriptive Statistics – Median: Partially Correct but Misleading
• The median is indeed a descriptive statistic, but so are mean, mode, range, variance, etc.
• Saying “Descriptive statistics – Median” is too narrow and implies that the median is the only or primary descriptive statistic, which is misleading.
• A better pairing would be “Descriptive statistics – Measures of central tendency” or “Descriptive statistics – Mean/Median/Mode.”

The correct answer is A-IV, B-III, C-II, D-I

Key Points

• ISDN (Integrated Services Digital Network) is a circuit-switched telephone network system that also provides access to packet-switched networks for digital transmission of voice and data, offering better quality than analog systems.
• ISDN supports data transmission in increments of 64 kilobits per second (kbit/s) and can provide up to 128 kbit/s bandwidth in both upstream and downstream directions, achieved through channel bonding.

​Types of ISDN Interfaces:

• Basic Rate Interface (BRI):
• ​BRI is designed for home and small office use.
• It consists of:
• 2 B-channels (Bearer channels) at 64 kbps each for voice/data
• 1 D-channel (Delta channel) at 16 kbps for signaling
• Total bandwidth: 144 kbps
• It’s the most basic ISDN configuration.
• Primary Rate Interface (PRI): 
• ​PRI is used in large organizations and enterprise-level telephony.
• In North America and Japan:
• 23 B-channels (64 kbps each)
• 1 D-channel (64 kbps)
• Total: 24 channels = 1536 kbps
• In Europe and elsewhere:
• 30 B-channels + 1 D-channel = 1984 kbps
• Broadband ISDN (B-ISDN): 
• Broadband ISDN (B-ISDN) was developed to support high-speed multimedia services.
• It uses ATM (Asynchronous Transfer Mode) for data transmission.
• B-ISDN goes beyond traditional ISDN by supporting video conferencing, high-speed internet, and other broadband services.

ISDN Services:

• Bearer Services:
• These services transfer information (voice, data, video) between users without altering the content.
• The network simply transmits the data without processing it, falling within the first three layers of the OSI model.
• Bearer services are defined in the ISDN standard and can operate using circuit-switched, packet-switched, frame-switched, or cell-switched networks.
• Teleservices:
• ​These services involve the network processing or changing the content of the data.
• They correspond to OSI layers 4-7 and rely on bearer services.
• Teleservices cater to complex user needs without requiring users to understand the details.
• Examples include telephony, telefax, teletex, telex, videotex, and teleconferencing. However, these services are not yet standardized in ISDN.
• Supplementary Services:
• These services add extra functionality to bearer and teleservices, such as reverse charging, call waiting, and message handling—common in modern telephone services.

Symmetric DSL Interface (ADSL) and Ultra-Advanced Rate Interface (UARI:

• ADSL and UARI are DSL technologies, not ISDN standards.
• They are used for broadband internet access, not for circuit-switched ISDN services.
• Hence, they are not part of the ISDN interface family.

The correct answer is B, A, C, D, E

Key Points

• There are six stages of reference interview and each stage is equally important.
• These stages are as follows:
• Stage 1: Establishing Rapport with the User.
• ​To establish rapport with the users, a reference librarian should possess certain identifiable attributes.
• Reference and User Services Association (RUSA) guidelines for the Behavioural Performance of Reference and Information Service Providers, list these attributes in five areas, viz. approachability, interest, listening/inquiring, searching, and follow-up.
• Stage 2: Discussing and Clarifying the Question:
• ​Once a dialog has started, the librarian should interact with the user and clarify the question posed by the user.
• The first and foremost activity is to repeat the question to ensure that the question posed by the user is the same as understood by the librarian.
• Then the reason for which information is sought and what the user has already done about it is to be enquired.
• Stage 3: Developing Strategy for Successful Search:
• ​Once the subject requirements of the user are clear, the librarian constitutes the search terms and identifies the most appropriate sources for the user.
• ​​Stage 4: Finding and Evaluating the Information:
• ​The next step is searching and locating the information.
• During the search process, the librarian should be in touch with the user to show the search results and find out if these meet his information requirements.
• This process should continue till the user gets the required information or has resources to examine.
• Stage 5: Follow-Up:
• ​Follow-up in the reference interview is essential, as it helps to know, whether information requirements of the user have been met or not.
• If the user query has not been answered to the user’s satisfaction, then revise the search terms or try other sources.
• Stage 6: Closing the Interview:
• ​Close the interview on a positive note.
• In case further information is required by the user, the librarian should give him/her a specific time frame to contact.
• In case of referral, the librarian should make an appointment with the concerned institution or experts and inform the user accordingly.

Additional Information

• A reference interview
• It is a conversation between a user who is in need of information and a librarian who assists in finding the required information.
• Reference interviews may be conducted in person, i.e., face-to-face, by telephone, or electronically such as e-mail, live chat, instant messaging (IM), or other electronic means as requested by the user.
• The Term Reference Interview was coined by Margaret Hutchins.

The correct answer is 1813.

Key Points

• The Charter Act of 1813, passed by the British Parliament, marked a key milestone in Indian education and the development of academic libraries.
• It required the East India Company to spend ₹1 lakh on promoting literature and science, initiating state-supported education in India.

Impact on Education and Libraries:

• Foundation of Institutions: Led to the establishment of colleges such as Hindu College (Calcutta, 1816), C.M.S. College (Kottayam, 1816), and Ravenshaw College (Cuttack, 1816), each with library facilities.
• Library Development: Serampore College (founded 1818) established a library at its inception and later gained university equivalence from Denmark.
• Expansion of English Education: A 1835 British Indian Government directive promoted English literature and sciences, resulting in over 40 colleges with libraries by 1839, including Presidency College (Madras, 1840) and a medical college in Bombay (1845).

The Charter Act of 1813 thus laid the foundation for academic libraries and higher education infrastructure in early 19th-century India.

The correct answer is A is not correct but R is correct.

Key Points

• Assertion A: POPSI depends on classification schedules to derive terms.
• Assertion A is NOT correct
• POPSI does NOT depend on classification schedules like DDC or CC.
• Instead, it is built on Ranganathan’s General Theory of Library Classification and uses a Classaurus, which is a controlled vocabulary tool—not a classification schedule.
• POPSI is designed to be independent of any fixed classification scheme. It uses analytical-synthetic methods to derive terms based on the structure of the subject itself (Discipline, Entity, Action, Property, Modifier).
• Reason R: Because it follows the same chain-building process as Chain Indexing.
• Reason R is correct
• POPSI does follow a chain-building process, but it’s not identical to Chain Indexing.
• The similarity lies in the synthetic construction of subject strings—both systems build index entries by combining elements in a structured way.
• However, POPSI’s process is more flexible and theory-driven, using postulates and principles rather than class number

The correct answer is Alpha Error

Key Points

• In hypothesis testing, an Alpha Error (Type I Error) occurs when a true Null Hypothesis is wrongly rejected.
• Since the researcher in this case has rejected the Null Hypothesis, the only possible error is a Type I error—that is, concluding that a significant effect exists when it actually does not.
• The probability of making this error is denoted by α (alpha), commonly set at levels such as 0.05.

Additional Information

• A Beta Error (Type II Error) occurs when a false Null Hypothesis is not rejected. As the Null Hypothesis has already been rejected here, a Beta Error cannot occur.
• Sampling error refers to natural differences between a sample and the population; it is not a hypothesis-testing decision error.
• Non-response error is a data collection issue arising when participants fail to respond and is unrelated to hypothesis-testing outcomes.

The correct answer is Nutrality Skewed

Key Points

• A Normal Probability Curve (also called the Gaussian distribution) has the following properties:
• Symmetrical about the mean → the left and right sides are mirror images.
• Zero Skewness → It is neither positively skewed nor negatively skewed.
• Mesokurtic in kurtosis → not leptokurtic (too peaked) or platykurtic (too flat).
• Mean = Median = Mode.

Additional Information

• Types of Probability Distributions
• A probability distribution describes how the values of a random variable are distributed and the likelihood of each possible outcome.
• Probability distributions are broadly classified into discrete and continuous distributions.

Discrete Probability Distributions: These distributions deal with countable values (such as 0, 1, 2, …).

• Binomial Distribution: It represents the probability of a fixed number of successes in a given number of independent trials, where each trial has only two outcomes (success or failure) and a constant probability of success.
• Poisson Distribution: Used to find the probability of a given number of events occurring in a fixed interval of time or space, assuming the events occur independently and at a constant average rate.
• Geometric Distribution: It gives the probability that the first success occurs on a specific trial in a sequence of independent trials.

Continuous Probability Distributions: These distributions apply to variables that can take any value within a given range.

• Normal Distribution: Also called the Gaussian distribution, it is symmetrical and bell-shaped. The mean, median, and mode are equal. It is widely used in social sciences, education, and natural sciences.
• Uniform Distribution: All values within a specified interval are equally likely. The graph of this distribution is rectangular in shape.
• (c) Exponential Distribution
• Used to measure the time between events in a continuous process where events occur independently at a constant average rate.

Skewed Distributions: When a distribution is not symmetrical, it is said to be skewed.

• Positively Skewed Distribution: The tail of the distribution extends to the right, and the mean is greater than the median.
• Negatively Skewed Distribution: The tail extends to the left, and the mean is less than the median.

Kurtosis-Based Distributions: These describe the peakedness of a distribution.

• Mesokurtic Distribution: Normal distribution with moderate peakedness.
• Leptokurtic Distribution: Highly peaked distribution with heavy tails.
• Platykurtic Distribution: Flat distribution with light tails.

The correct answer is ALA

Key Points

The Library Bill of Rights:

• The Library Bill of Rights, established by the American Library Association (ALA), articulates the fundamental rights of library users and the responsibilities of libraries to uphold these rights.
• Initially adopted in 1939 and subsequently amended over the years, the document encompasses principles such as providing access to diverse materials, opposing censorship, safeguarding privacy, and ensuring equitable access to library resources and services.
• The present Library Bill of Rights, with its interpretive documents, recognizes that censorship of any materials, in any guise, eventually affects the library.

Key provisions include:

• Ensuring that library resources cater to the interests and enlightenment of all community members, without discrimination based on the contributors' backgrounds or views.
• Presenting materials representing diverse viewpoints and resisting efforts to restrict or remove content due to ideological differences.
• Taking a stand against censorship and advocating for freedom of expression and access to information.
• Collaborating with individuals and groups to defend free expression and access to ideas.
• Guaranteeing everyone's right to use the library, regardless of their background or beliefs.
• Providing exhibit spaces and meeting rooms impartially, irrespective of the beliefs or affiliations of requesting individuals or groups.
• Safeguarding individuals' right to privacy and confidentiality in their library use, including protecting personal data.

Additional InformationFreedom to Read Statement:

• Similarly, the Freedom to Read Statement, conceived in 1954, asserts that the freedom to read is indispensable to democracy.
• Originating from discussions among educators, librarians, publishers, and others concerned about censorship, it outlines the responsibilities of publishers and librarians in preserving Americans' right to read.
• Over time, it has adapted to confront challenges like violence and legal prosecution, standing as a steadfast assertion of the literary community's commitment to freedom of choice in reading materials.

The correct answer is Fundamental Research

Key Points

• Jean Piaget developed his theory of cognitive development through fundamental research, paying special attention to the kinds of mistakes children made at different ages.
• He believed that intelligence develops qualitatively, not just quantitatively, and proposed that children move through distinct stages of cognitive growth.
• His theory is based on the following key aspects:
• Systematic observation: Piaget closely observed children, including his own, to understand how their thinking changes with age.
• Genetic epistemology: He studied how knowledge originates and develops in human beings.
• Clinical method: Piaget used open-ended questions and problem-solving tasks to explore children’s reasoning and identify patterns in their errors.
• Developmental stages: He proposed four stages of cognitive development—sensorimotor, preoperational, concrete operational, and formal operational—each representing a different way of thinking and understanding the world.

Additional Information

• Jean Piaget’s theory explains cognitive development as a step-by-step progression through four stages, with each stage representing a more advanced way of thinking than the previous one.
• Sensorimotor Stage (Birth to 2 years): In this stage, children understand the world through sensory experiences and physical actions such as touching, grasping, and looking. Knowledge is built by coordinating what they see with what they do.
• A major achievement of this stage is object permanence, the realization that objects continue to exist even when they are out of sight.
• Preoperational Stage (2 to 7 years): Children begin to use language and symbols to represent objects and ideas, but their thinking is not yet logical.
• They have difficulty understanding conservation, often judging quantity by appearance rather than actual amount.
• Thinking is also largely egocentric, meaning children struggle to see situations from perspectives other than their own.
• Concrete Operational Stage (7 to 11 years): At this stage, thinking becomes more logical and organized, but it is still tied to concrete objects and experiences.
• Children understand conservation and can classify objects.
• They develop the ability to mentally reverse actions and show a better understanding of others’ viewpoints.
• Formal Operational Stage (11 years and above): Adolescents gain the ability to think abstractly and hypothetically.
• They can solve complex problems, consider “what-if” situations, and reason systematically.
• This stage allows for advanced thinking in areas such as science, mathematics, ethics, and philosophy.

The correct answer is z – Generalia, O – Literature, Z – Law

Key Points

• In the standard CC 6th edition lists, this usually refers to classes like Generalia, Literature, and Law).
• In S.R. Ranganathan’s Colon Classification (CC), the concepts of Rounds and Levels are used to handle the manifestation of fundamental categories (PMEST).
• Rounds: These occur when a fundamental category (usually Energy) repeats itself in a formula (E, 2E, 3E).
• Personality, Matter, and Space can appear in different rounds.
• Levels: These occur when a fundamental category (P, M, S, T) manifests more than once within the same round (e.g., P1, P2, P3).
• Analysis of the Main Classes:
• The classes that typically have only Levels and No Rounds are those where the Energy (E) facet does not act as a "separator" to start a new cycle of facets.
• Generalia (z): Primarily uses levels of personality.
• Literature (O): The facet formula is [O], [P], [P2], [P3], [P4].
• It contains four levels of Personality (Language, Form, Author, Work) but no Rounds because there is no Energy facet to initiate a second round.
• Law (Z): The facet formula is [Z], [P], [P2], [P3], [P4].
• Similar to Literature, it consists of levels of Personality (Community, Law, etc.) without entering subsequent rounds.

The correct answer is A-III, B-IV, C-II, D-I

Key Points

Additional Information

Levels of Measurement

• There are four levels (scales) of measurement used to classify and analyse data.
• Each scale represents a different way of measuring variables, from simple identification to precise numerical comparison.

Nominal Scale

• The nominal scale is the most basic level of measurement. Here, numbers or labels are used only to identify or classify objects. They do not indicate quantity or order.
• Key features:
• Data are divided into categories
• Qualitative in nature
• Numbers act only as labels
• Counting is the only possible numerical operation

Ordinal Scale

• The ordinal scale not only classifies data but also ranks it in a meaningful order. However, the exact difference between ranks is not known.
• Key features:
• Shows relative position or ranking
• Indicates order but not the magnitude of the difference
• Qualitative or categorical data

Interval Scale

• The interval scale is a quantitative scale where the difference between values is meaningful, but there is no true zero point.
• Key features:
• Equal intervals between values
• Zero point is arbitrary
• Addition and subtraction are meaningful

Ratio Scale

• The ratio scale is the highest level of measurement. It has all the properties of an interval scale, along with a true zero, which allows for complete mathematical operations.
• Key features:
• Absolute zero point
• No negative values
• Supports all arithmetic operations

The correct answer is A-IV, B-II, C-III, D-I

Key Points

Additional Information

• George Marcus introduced the concept of multi-sited ethnography in his influential 1995 article “Ethnography in/of the World System: The Emergence of Multi-Sited Ethnography.”
• He argued that ethnographic research should move beyond a single location and instead follow people, objects, ideas, and relationships across multiple sites.
• This approach reflects the interconnected and globalized nature of contemporary social life.
• Clifford Geertz advanced ethnographic theory through the idea of “thick description,” presented in The Interpretation of Cultures (1973).
• He emphasized that ethnography is not simply about observing behavior but about interpreting the cultural meanings embedded in social actions.
• Thick description seeks to uncover the symbolic “webs of significance” that give actions their context and meaning.
• Bronislaw Malinowski is regarded as the founder of modern ethnographic fieldwork and a key figure in functionalist anthropology.
• His long-term participant observation in the Trobriand Islands between 1915 and 1918, documented in Argonauts of the Western Pacific (1922), established immersive fieldwork as the core method of ethnography.
• Malinowski viewed cultural practices as serving essential functions that sustain social life.
• Émile Durkheim conceptualized society as a social organism, arguing that it exists independently of individuals and functions through interconnected institutions.
• According to Durkheim, these institutions operate like specialized organs, working together to maintain social order and stability.
• He also viewed social evolution as a movement from simple to more complex and interdependent forms.

The correct answer is May 2008

Key Points

• Convention on the Rights of Persons with Disabilities (CRPD):
• ​The Convention on the Rights of Persons with Disabilities (CRPD) and its Optional Protocol (A/RES/61/106) were adopted by the United Nations on 13 December 2006 and opened for signature on 30 March 2007 at UN Headquarters, New York.
• On its opening day, the Convention received 82 signatories, while the Optional Protocol had 44 signatories, along with one ratification—the highest number ever recorded for a UN convention at the time of opening.
• The Convention entered into force on 3 May 2008.
• It is the first comprehensive human rights treaty of the 21st century and the first to allow signature by regional integration organizations.
• The CRPD represents a major shift in global thinking about disability. It moves away from viewing persons with disabilities as objects of charity, medical care, or social protection, and instead recognizes them as rights-holders capable of making informed decisions and actively participating in society.
• The Convention emphasizes dignity, autonomy, and inclusion based on free and informed consent.
• The Convention was negotiated through eight sessions of an Ad Hoc Committee of the UN General Assembly between 2002 and 2006, making it one of the fastest-negotiated human rights treaties in UN history.

The correct answer is A, B, D only

Key Points

• The CeCILL Free Software License Agreement was initiated and jointly developed by three major French public research organizations: the
• CEA (Atomic Energy Commission),
• CNRS (National Centre for Scientific Research), and
• INRIA (National Institute for Research in Digital Science and Technology).
• The name CeCILL is derived from these institutions—Ce (CEA), C (CNRS), I (INRIA), and LL (Logiciel Libre, meaning Free Software).
• CeCILL was designed to address both French and international legal requirements while remaining compatible in spirit with the GNU General Public License (GPL).
• It was officially announced on 5 July 2004 through a joint press release by the three agencies.
• The license gained strong support from the French open-source community, including major Linux User Groups, and received endorsement from the French Minister for the Civil Service.
• It was also considered for adoption at the European level before the creation of the European Union Public Licence (EUPL).
• In addition to the main CeCILL license, the project introduced two variants to address specific licensing needs:
• CeCILL-B: Compatible with BSD-style licenses (such as BSD, MIT, and X11). It includes strong attribution requirements that may conflict with GPL terms unless dual licensing is used.
• CeCILL-C: Intended for software components and fully compatible with the GNU LGPL, making it suitable for libraries.
• Both CeCILL-B and CeCILL-C were created to ensure that BSD-like and LGPL licenses are enforceable internationally under WIPO legal frameworks.

The correct answer is Both A and R are correct and R is the correct explanation of A.

Key Points

• Assertion A: A cross-table is a numerical tabular presentation of data, usually in frequency or percentage form in which variables are cross-partitioned to study relations between them.
• This is a precise definition of a cross-tabulation, also known as a cross-break table or contingency table. Here's what it means:
• It presents data in a matrix format: rows and columns represent different variables.
• Each cell shows a frequency count or percentage.
• It is used to analyze relationships between two or more categorical variables.
• Common in survey, market, and social science research.
• Example: If you want to study the relationship between gender and preferred news source, a cross break table would show how many males and females prefer each source.
• Reason R: The categories are set up according to the research hypothesis
• This is also correct and explains the logic behind the structure of a cross break table:
• The research hypothesis guides which variables are selected and how they are categorized.
• For example, if your hypothesis is “Age influences political preference,” you’ll categorize data by age groups and political choices.
• This ensures the table is purposefully structured to test the hypothesis.
• How R Explains A
• Assertion A tells us what a cross-break table is.
• Reason R tells us why the table is structured the way it is — to test a hypothesis.
• Therefore, R is not just correct, but it directly explains the rationale behind A.

The correct answer is E, C, A, B, D

Note: The official answer key mentioned both 1 and 3 options as correct answers; both options contained some discrepency so we have modified the options.

Key Points

• Biometric Scanner (Shortest): Usually requires physical contact (fingerprint) or very close proximity (0–5 cm for iris/face) to ensure high-fidelity data capture for security.
• NFC (Near Field Communication): As the name suggests, it is designed for "near" fields. It operates via magnetic induction and usually fails beyond 10 cm.
• Barcode (1D): Uses a laser or LED to read reflected light. Standard library scanners typically work within 10 cm to 1 meter.
• QR Code (2D): Because it is an image-based pattern with high error correction, a high-resolution camera can read a large QR code from several meters away (up to 10+ meters).
• RFID (Longest): Uses radio waves. Even "Passive" RFID tags used in libraries can be read from 3–5 meters, while "Active" tags can reach 100+ meters.

The correct answer is Ex post facto method

Key Points

Ex Post Facto Method

• Literally means “after the fact.”
• In this method, the researcher selects the independent variable but does not manipulate it, because the events or conditions have already occurred.
• The researcher studies the effect of a naturally occurring independent variable on a dependent variable.
• Example: Studying the effect of smoking (independent variable, already occurred) on lung health (dependent variable).

Additional Information

• Experimental Method
• In experimental research, the researcher manipulates the independent variable to observe its effect on the dependent variable.
• Example: Changing teaching methods (independent variable) to see their effect on student performance (dependent variable).
• Descriptive Survey Method
• This method involves collecting data to describe characteristics of a population or phenomenon.
• It does not manipulate variables, but it also does not focus on selecting independent variables for causal analysis—it’s more about description.
• Exegetic Method
• This is more of an interpretive or analytical method, often used in textual or qualitative research.
• It does not deal with independent/dependent variable manipulation in the same sense as quantitative methods.

The correct answer is ​Voice and Data Traffic.

Key Points

• In ISDN Basic Rate Interface (BRI), the B (Bearer) channels are used to carry user information such as voice, data, and video.
• Each B channel operates at 64 Kbps, and two B channels are available in BRI.
• These channels can be used independently or combined (bonded) to achieve a total data rate of 128 Kbps, allowing multiple services to be transmitted simultaneously over a single line.
• The main uses of B channels include voice transmission for digital telephone calls, data transfer such as file sharing and internet access, and video communication like video conferencing.
• They also support circuit-switched connections, enabling one channel to be used for a data connection while the other is used for a voice call at the same time.

Additional Information

• ISDN (Integrated Services Digital Network) is a circuit-switched telephone network system that also provides access to packet-switched networks for digital transmission of voice and data, offering better quality than analog systems.
• ISDN supports data transmission in increments of 64 kilobits per second (kbit/s) and can provide up to 128 kbit/s bandwidth in both upstream and downstream directions, achieved through channel bonding.

​Types of ISDN Interfaces:

• Basic Rate Interface (BRI): Includes two 64 Kbps B channels for data and one 16 Kbps D channel for signaling. BRI provides a total bandwidth of 144 Kbps (with overhead).
• Primary Rate Interface (PRI): Offers 23 or 30 B channels (depending on the country), each 64 Kbps, and one D channel at 64 Kbps. PRI provides a bandwidth of 1.536 Mbps, with some overhead.
• Broadband ISDN (B-ISDN): Relies on fiber optics and is designed to provide higher speeds than narrowband ISDN, using advanced technology for wider bandwidth services.

The correct answer is Audio files

Key Points

• The AIFF (.aif, .aiff, .aifc) file format is primarily used for storing high-quality, lossless audio on Apple Macintosh systems and in professional audio production environments.
• It is the standard uncompressed PCM (Pulse Code Modulation) format on macOS and is widely used in recording, editing, and mastering because it preserves original sound quality without compression.
• AIFF offers high audio fidelity since it is uncompressed, making it superior in quality to lossy formats like MP3.
• It also supports rich metadata, including artist name, album details, track titles, and album artwork.
• The .aif/.aiff formats are typically uncompressed, while .aifc (AIFF-C) is a compressed version used when reduced file size is required.
• Functionally, AIFF is to Apple what WAV is to Windows—both are professional-grade, uncompressed audio container formats used for high-quality sound storage and production.
