MARC Tag Usage


OCLC will examine MARC tag usage in the WorldCat database.The goal of this new MARC Usage in WorldCat activity is to provide an evidence base for testing assertions about the value of capturing various attributes by demonstrating whether the cataloging community has made the effort to populate specific tags, not just to define them in anticipation of use.

OCLC Research seeks to use evidence of usage, as depicted in WorldCat, the largest aggregation of library data in the world, to inform decisions about where we go from here with the data that has been encoded using the MARC standard.
