    No. The NUCMC cooperative cataloging project began in 1959. From 1959 to 1993, the NUCMC catalog was produced as printed volumes. In 1986, NUCMC staff began using the RLG Union Catalog (now defunct) to produce its published catalog -- from 1986 - 1993, NUCMC records are available both online through OCLC WorldCat and in the printed volumes. Beginning in 1993, records created by NUCMC catalogers are only available in OCLC WorldCat.

Chadwyck-Healey has also published an Index to Personal Names in the National Union Catalog of Manuscript Collections, 1959-1984 (2 v., 1988), and an Index to Subjects and Corporate Names in the National Union Catalog of Manuscript Collections, 1959-1984 (3 v., 1994). Check with your local library to locate these indexes.

The Library does not provide "free" access to search books or other types of material in WorldCat.
