Cataloguing and Metadata

Library & Information Science

Useful for: Rajasthan PTI / Librarian

Overview

Cataloguing describes library materials so users can find them; metadata standards make records shareable across systems.

Key points

  • AACR2 was the standard cataloguing code; RDA (Resource Description and Access, 2010) replaced it.
  • MARC 21 is the machine-readable format for catalogue records.
  • Dublin Core has 15 basic metadata elements.
  • ISBN has 13 digits since 2007.
  • OPAC (online public access catalogue) lets users search the catalogue.
  • Access points include author, title and subject.

Explanation

  • Authority control keeps names and subjects consistent.
  • Subject headings use controlled vocabularies.
  • Copy cataloguing reuses existing records.
  • ISSN identifies serials (8 digits).
  • Good metadata improves discovery.

Step by step

  1. Identify the concept, rule or fact asked.
  2. Recall the definition, formula, example or year.
  3. Apply it and eliminate mismatched options.

Examples

  • Metadata scheme with 15 elements → Dublin Core.
  • Machine-readable catalogue format → MARC 21.
  • Digits in ISBN today → 13.

Traps and advanced points

  • Trap: Mixing ISBN and ISSN.
  • Trap: Calling AACR2 current.
  • Trap: Ignoring authority control.

Quick revision

  • AACR2 → RDA (2010).
  • MARC 21; Dublin Core 15.
