About this event


A format for describing resources in any form

Part 1: October 3, 2022 | 10:00am - 2:30pm (Pacific)

Part II: October 10, 2022 | 10:00am - 2:30pm (Pacific)

Presenter: Rebecca Guenther, Metadata Consultant at Rebecca Guenther Consulting (she/her/hers)

MARC (Machine-Readable Cataloging) is a computer file format that allows for the description of bibliographic resources in any media format, e.g. books, serials, audio, video, computer files, etc. Part 1 (the first session) covers the development of MARC from its beginnings in 1968 through the present. This includes the development of special formats for all types of media and the process of integrating these formats into an international format used for communicating bibliographic descriptions between institutions. Thanks to bibliographic utilities such as OCLC, bibliographic data is exchanged worldwide. The history of MARC is described, including the MARC change process and the structure of MARC. How MARC is used for audiovisual material is reviewed, and its relationship to cataloging rules is discussed. Part 2 describes the MARC environment, including record sharing, and the development of MARC systems that support the bibliographic format and the authority, community information, holdings, and classification formats are introduced. More recent developments of XML formats, such as MARCXML and MODS, and the development of Dublin Core are introduced. The need for a new format that integrates with other systems on the Web is described, and that format is BIBFRAME. The session will include exercises using MARC data elements in general and how they're used for audiovisual material.

Topics That Will Be Covered:

  • History of MARC
  • Structure of MARC
  • Application of MARC for audiovisual material
  • MARC and cataloging rules
  • The MARC environment
  • XML formats and MARC
  • MARC systems
  • Integrating with other systems on the Web
