UGC NET Law Unit - V Syllabus

List the ten main classes (000-900) of DDC.

000 Computer science/Information/General; 100 Philosophy & Psychology; 200 Religion; 300 Social sciences; 400 Language; 500 Science; 600 Technology; 700 Arts & Recreation; 800 Literature; 900 History & Geography.

What are the auxiliary tables in DDC used for?

They provide standard subdivisions/notations (e.g., Table 1 Standard Subdivisions, Table 2 Geographic Areas) that are added to base numbers to specify aspects like place, language, or form.

What is the Universal Decimal Classification (UDC) and who developed it?

A faceted (analytico-synthetic) general classification developed by Paul Otlet and Henri La Fontaine (1905), based on an expansion of DDC.

Name three common UDC connecting/auxiliary symbols and their meanings.

+ (addition/coordination of two subjects), / (extension, consecutive range), : (relation between two subjects); also () for place, '' for time, = for language.

State one major difference between DDC and UDC.

DDC is largely enumerative and uses pure decimal numbers; UDC is analytico-synthetic (faceted), allowing complex number building with auxiliary signs and using mixed punctuation.

What is Colon Classification (CC), who devised it, and when?

A fully faceted/analytico-synthetic classification devised by S. R. Ranganathan, first published in 1933.

What type of notation does Colon Classification use?

A mixed notation using Roman letters, Arabic numerals, Greek letters, and punctuation marks (the colon and other connecting symbols) to express PMEST facets.

What is the difference between a catalogue and a bibliography?

A catalogue lists documents held in a particular library/collection (location-specific), while a bibliography lists documents on a subject/by an author regardless of where they are held.

What is centralized cataloguing?

A system in which catalogue records are prepared at one central agency (e.g., Library of Congress) and supplied to many libraries, avoiding duplication of effort.

What is cooperative cataloguing?

An arrangement where several libraries share the work of creating and contributing original catalogue records to a common pool/database (e.g., OCLC), reducing redundant cataloguing.

What is CCC (Classified Catalogue Code), who created it, and what catalogue type does it support?

Classified Catalogue Code by S. R. Ranganathan (first published 1934); it provides rules for a classified catalogue (entries arranged by class number with an alphabetical index).

What does AACR2 stand for, and which bodies sponsored it?

Anglo-American Cataloguing Rules, 2nd edition — sponsored by the American Library Association, the (British) Library Association, and the Library of Congress; published 1978 (revised 1988, 1998, 2002).

On what two principles is the description in AACR2 based?

It is based on the ISBD framework (for bibliographic description) and on the concept of main entry/added entries with the 'rule of three' for authorship.

What does ISBD stand for and what is its purpose?

International Standard Bibliographic Description — an IFLA standard that prescribes the elements, order, and punctuation for describing library materials to enable international exchange of records.

Name the eight areas of bibliographic description in ISBD.

1 Title & statement of responsibility; 2 Edition; 3 Material/type-specific details; 4 Publication/distribution; 5 Physical description; 6 Series; 7 Notes; 8 Standard number & terms of availability.

What is MARC 21 and what does MARC stand for?

MAchine-Readable Cataloging, 21st century — a standard data format (developed by LC) for representing and exchanging bibliographic, authority, holdings, classification, and community information records in machine-readable form.

What are the three main components of a MARC 21 record structure?

The Leader, the Directory, and the Variable fields (variable control fields and variable data fields with tags, indicators, and subfield codes).

In MARC 21, what do common tags 100, 245, and 260/264 represent?

100 = Main entry (personal author); 245 = Title statement; 260/264 = Publication/distribution (imprint) information.

What is the Common Communication Format (CCF)?

A standard bibliographic exchange format developed under UNESCO (1984) to allow exchange of records between libraries and information/abstracting agencies; based on ISO 2709.

What does RDA stand for and what is it?

Resource Description and Access — the content/cataloguing standard (released 2010) that replaced AACR2, built on the FRBR and FRAD conceptual models and designed for the digital/linked-data environment.

What conceptual model underpins RDA?

FRBR (Functional Requirements for Bibliographic Records) together with FRAD; now updated to the IFLA Library Reference Model (LRM).

What does FRBR stand for and who developed it?

Functional Requirements for Bibliographic Records — developed by IFLA (final report 1998).

Name the four entities of FRBR's Group 1 (the products of intellectual/artistic endeavour).

Work, Expression, Manifestation, and Item (WEMI).

What are FRBR's Group 2 and Group 3 entities?

Group 2: Person, Corporate body (entities responsible for content/production). Group 3: Concept, Object, Event, Place (entities that serve as subjects of a work).

What are the four generic user tasks defined by FRBR?

Find, Identify, Select, and Obtain.

What is BIBFRAME and who developed it?

Bibliographic Framework — a linked-data model (RDF-based) developed by the Library of Congress (2012 onward) intended to replace the MARC 21 formats for the web/Semantic Web environment.

Name the three core classes/levels of the BIBFRAME model.

Work, Instance, and Item (with Agents, Subjects, and Events as related entities).

What is ISO 2709?

An ISO standard specifying the structure (record label, directory, and data fields) for bibliographic information interchange records on magnetic/electronic media; it is the underlying structure of MARC and CCF.

What is Z39.50?

A NISO/ISO 23950 client-server protocol for information retrieval that allows a user to search and retrieve records from remote databases (e.g., other library catalogues) using a single interface.

What does the standard Z39.71 cover?

It is the NISO standard for Holdings Statements for Bibliographic Items (describing a library's holdings of serials and other multipart items).

What is Dublin Core and how many basic elements does it have?

A simple, interoperable metadata standard for describing digital and web resources, consisting of 15 core elements (e.g., Title, Creator, Subject, Date, Identifier).

List five of the fifteen Dublin Core metadata elements.

Any five of: Title, Creator, Subject, Description, Publisher, Contributor, Date, Type, Format, Identifier, Source, Language, Relation, Coverage, Rights.

What is METS and what is its purpose?

Metadata Encoding and Transmission Standard — an XML schema (maintained by LC) for encoding descriptive, administrative, and structural metadata of objects within a digital library.

What is MODS and how does it relate to MARC?

Metadata Object Description Schema — an XML descriptive metadata standard (LC) that carries selected MARC 21 data using language-based tags rather than numeric tags; richer than Dublin Core but simpler than full MARC.

What is EAD and what is it used for?

Encoded Archival Description — an XML standard for encoding archival finding aids (descriptions of archives and manuscript collections), maintained by the Library of Congress with the Society of American Archivists.

What is a pre-coordinate indexing system?

An indexing system where index terms are combined/coordinated by the indexer at the input (indexing) stage to form composite subject headings (e.g., chain indexing, PRECIS, subject headings).

What is a post-coordinate indexing system?

A system where single concept terms are stored separately and combined by the searcher at the output (search) stage using Boolean logic (e.g., uniterm, keyword systems).

Distinguish 'assigned' indexing from 'derived' indexing.

Assigned indexing uses terms chosen from a controlled vocabulary applied by the indexer; derived indexing extracts index terms directly from the document text/title (e.g., KWIC/title-based indexing).

What is a title-based derived indexing system? Give an example.

An indexing method that generates index entries automatically from the words of a document's title; examples include KWIC (Keyword in Context) and KWOC (Keyword out of Context).

What is vocabulary control and why is it important?

The use of a controlled, standardized list of terms (with chosen preferred terms and managed synonyms/homonyms) to ensure consistency in indexing and retrieval, improving recall and precision.

Name the three standard equivalence/relationship types displayed in a thesaurus (vocabulary control tool).

Equivalence (USE / UF), Hierarchical (BT broader term / NT narrower term), and Associative (RT related term).

What two devices are used in vocabulary control to handle synonyms and homographs?

Synonyms are controlled with USE/UF (equivalence) references to a single preferred term; homographs (same spelling, different meaning) are distinguished by qualifiers/scope notes.

What is a scope note in a controlled vocabulary?

A note attached to a term that clarifies its intended meaning and restricts its usage within the indexing language to ensure consistent application.

Name the standard for monolingual thesaurus construction guidelines.

ISO 25964 (Thesauri and interoperability with other vocabularies); earlier ISO 2788 (monolingual) and ISO 5964 (multilingual).

In OPAC/catalogue evaluation, what does 'precision' measure?

Precision = the ratio of relevant documents retrieved to the total number of documents retrieved (a measure of retrieval accuracy/quality).

In information retrieval evaluation, what does 'recall' measure?

Recall = the ratio of relevant documents retrieved to the total number of relevant documents in the collection (a measure of retrieval completeness).

What is the typical relationship between recall and precision in retrieval systems?

They are usually inversely related: increasing recall (retrieving more) tends to lower precision, and increasing precision tends to lower recall.

What is a catalogue code and name two functions it serves?

A set of rules for preparing catalogue entries; it ensures (1) consistency/uniformity of records and (2) standardization enabling cooperative and centralized cataloguing and exchange.

What are the four canons for the idea plane that govern choice of characteristics in classification (Ranganathan)?

Canon of Differentiation, Canon of Concomitance, Canon of Relevance, and Canon of Ascertainability.

What is 'notation' in a classification scheme and name two desirable qualities of good notation.

Notation is the system of symbols used to represent classes and their order. Good notation should be brief (short) and mnemonic, as well as hospitable and expressive.

What is hospitality in a classification notation?

The capacity of the notation to accommodate (insert) new subjects in their correct logical place, both in array (coordinate classes) and in chain (subordinate classes), without disturbing existing numbers.

What does Library of Congress Subject Headings (LCSH) exemplify in indexing?

It is a pre-coordinate, controlled-vocabulary subject heading list (an assigned indexing language) maintained by the Library of Congress.

What is the difference between MARC 21 and BIBFRAME in terms of data model?

MARC 21 is a flat, record-based exchange format tied to ISO 2709; BIBFRAME is an RDF linked-data model expressing relationships between Work/Instance/Item entities for the Semantic Web.

What components make up a complete catalogue entry under AACR2/ISBD description?

Heading (access point), bibliographic description (the eight ISBD areas), tracings (added entries), and the call number/location.

What is chain indexing and who developed it?

A pre-coordinate subject indexing technique developed by S. R. Ranganathan that derives subject index entries from the chain of successive subordinate classes of a classification number.

What is the role of the Library Reference Model (LRM) introduced by IFLA in 2017?

It consolidates the earlier FRBR, FRAD, and FRSAD models into a single, harmonized conceptual reference model for bibliographic information, underpinning current RDA.
