Abstract

Provides all valid LC rule interpretations issued since the AACR2 1988 revision. All rule numbers cited are referenced to AACR2 revision. Rule interpretations are written to ensure uniform and consistent application of cataloging rules set forth in AACR2. A revised index with each quarterly update highlights significant schanges

Abstract

Format specifications for the communication of MARC classification records, which may be used in online public catalog retrieval systems, in systems to maintain and develop classification schedules, and in online systems for library classifiers. Defines the codes and conventions (tags, indicators, subfield codes, and codes values) that identify the data elements in the records. Developed to support the 2 major US classification schemes: Library of Congress Classification and Dewey Decimal Classification, but also lets you communicate other classification schemes. Includes a glossary of classification terms and full record examples of LCC, DDC, NLM classification and UDC

Abstract

Includes changes to all examples throughout the publication, as approved by MARBI in January 1993. Makes obsolete the second indicator position (non-filing characters) in all of the heading fields except the 130, which is uniform titles. Also new to this edition: definition of 18X heading fields for general, geographic and chronological subdivision headings, plus related 48X and 58X fields... 7XX fields for heading-linking entries... and the control field 003, named the 'control number identifier.' Also eliminates the national-level requirement codes at the field level

Abstract

Here is the standard for representing and exchanging bibliographic data in machine-readable form in the United States. This comprehensive publication defines the structure of the MARC bibliographic record in full detail. Also defines the codes and conventions (tags, indicators, subfield codes and codes values) that identify the data elements in USMARC bibliographic records. Includes specifications for a National Level Bibliographic record (both full and minimal). The remaining future format integration changes are specified
