Abstract

This paper describes the work of the MARC Content Designation Utilization (MCDU) Project, funded by a National Leadership Grant from the U.S. Federal Institute of Museum and Library Services (IMLS). The MCDU Project is analyzing approximately 56 million MARC 21 Format for Bibliographic Data records from OCLC's WorldCat database to identify actual use of the content designation available in the MARC bibliographic record. We consider bibliographic records as artifacts resulting from the overall cataloging enterprise, of which the encoding of the bibliographic data into MARC is only one part. Concepts from the Functional Requirements for Bibliographic Records (FRBR) can be used to examine and critically assess the availability of bibliographic data in these records, data meant to assist end users in finding, identifying, selecting, and obtaining relevant information resources. Overall, the MCDU Project will provide empirical data reflecting the actual use of MARC content designation structures in this set of records. Specifically, the data can be used to demonstrate how catalogers' coding of bibliographic data may or may not assist end users in these four tasks. The project is using the mapping by Delsey of MARC data elements to FRBR user tasks in this analysis. These data are crucial for making decisions about the future of MARC and may inform current work on bibliographic rules reflected in the development of the next version of cataloging rules (i.e., Resource Description and Access) by the Joint Steering Committee for the Revision of the Anglo-American Cataloguing Rules.
