Title National Union Catalog, pre-1956 imprints
Coverage Dates 1500-1955
Notes "Compiled and edited with the cooperation of the Library of Congress and the National Union Catalog Subcommittee of the Resources and Technical Services Division, American Library Association." -- title page.
Coverage includes libraries in the United States and Canada.
This work is the centerpiece for verification of books and other materials prior to 1956. Because many major research libraries have not converted major portions of their collections into electronic formats, this source will need to be consulted for years to come. It is also important to use NUC to verify serial titles which were closed prior to 1956. These titles may or may not have been covered in the Union List of Serials.
Check supplement volumes for additions to original cumulation, especially for early parts of the alphabet.
