Program: How MAchine-Readable Cataloging (MARC) Works

Program Description:

MARC is a data format that uses a system of numbers, letters, and symbols to store and exchange bibliographic information. Developed in the 1960s, MARC is the basis of most library OPACs, and therefore essential for understanding how catalogs work. This workshop is designed for anyone interested in learning about the structure and content of cataloging records.  You will learn how to “read” a MARC record, and understand the relationship between cataloging in Voyager and data display in the OPAC. Topics include:  1) MARC formats and their structure, 2) how MARC represents bibliographic information, and 3) how what catalogers do impacts what users see.
