Can Ulrichs Subject Headings be used to catalog serials in the OPAC?
Ulrich’s predates MARC format, and was never designed to be a MARC cataloging database. However, some librarians choose to include Ulrich’s subjects in their MARC 69X fields as local subjects on their primary catalog records. Including Ulrich’s subjects in their MARC records provides an additional point of reference (and linking) between catalog records and a library’s Ulrich’s products.
