Are all NUCMC records accessible in one single online catalog?
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.
