Chapter 4 : Organization and Access to Information in Library

Processing of Library Materials

  • Technical processing = behind-the-scenes work that prepares items for patron use.
  • Core functions:
    • Acquisition • Cataloging • Classification • Physical processing • Data entry & automation • Preservation/repair • Weeding & de-selection
  • Primary goals: organized, accessible, maintained collections ⇒ quick retrieval, inventory control, positive user experience.

Library Catalog

  • Definition: inventory & discovery tool for all holdings; most common form today = OPAC.
  • OPAC record fields: Title, Author, Publication info, Subject headings, Call number, Availability, Location.
  • User uses: locate items, explore topics, check status, access e-resources.
  • Staff uses: collection management, cataloging, stats, resource sharing.

Main Components (Online Environment)

  • Bibliographic description
  • Classification & call numbers
  • Resource type/format
  • Subject headings/keywords
  • Availability status & digital links
  • OPAC ↔ LMS (Integrated Library System) ↔ MARC work together:
    • LMS modules: Cataloging, Circulation, Acquisition, User management, Reporting
    • MARC = standard record structure (e.g. 100 Author, 245 Title, 650 Subject, 082/050 Call no.)

Traditional Card Catalog

  • Four core elements:
    1. Heading/Main entry
    2. Description (ISBD punctuation)
    3. Tracing (subject & added entries)
    4. Call number (DDC/LCC)

Cataloging

  • Purpose: create bibliographic records to populate catalog.
  • Basic steps:
    1. Prepare main entry & added entries (primary vs. alternative access points).
    2. Describe item (descriptive cataloging) using AACR2 or RDA + ISBD areas.
    3. Assign subject headings (LCSH, Sears, MeSH).
    4. Assign call number (DDC, LCC, UDC).
    5. Write tracing (records of all added entries, esp. for card catalog).
    6. Prepare authority files & reference entries (name, subject, title control).

Descriptive Cataloging Essentials (Step 2)

  • Follows ISBD; 8 description areas ensure cross-library consistency.
  • Common ISBD variants: ISBD(M) monographs, ISBD(ER) electronic, etc.

Authority Control (Step 6)

  • Authority files = authorized forms; guarantee consistency & disambiguation.
  • Reference entries: “See” (variants → authorized), “See also” (related terms).

Cataloging Tools

  • Standards & rules: AACR2, RDA, ISBD.
  • Subject tools: LCSH, Sears, MeSH.
  • Classification: DDC, LCC, UDC.

Key Takeaways

  • Technical processing underpins library service quality.
  • Catalog = central access tool; OPAC records built on MARC inside an LMS.
  • Effective cataloging relies on standardized rules, subject vocabularies, and classification schemes to ensure discoverability across physical & digital environments.
