Evaluating Bibliographic Resources National Union Catalog
NUC’s Beginning • In 1901, the Library of Congress attempted to put together a catalog of all the important books in American libraries • Over 11 million catalog cards were copied & distributed to libraries across the country • Eventually, these cards were reproduced and issued serially in printed volumes with the name “National Union Catalog”
NUC’s Evolution • To simplify this huge task and massive bibliography, all pre-1956 American & Canadian imprints were alphabetized by author and printed into 754 volumes • These volumes total over 528,000 pages, take up 130 feet of shelf space, and weigh over 3 tons • They can be found in over 1100 libraries in America & Canada
Very thorough record of pre-1956 books before digital cataloging databases Massive size makes this bibliography difficult to use Pros & Cons
Evaluation of NUC • Accuracy: it is an accurate representation – it began as a reproduction of catalog cards that were sent to libraries across the country so that anyone could find bibliographic information on virtually every book

Evaluation of NUC • Scope: It has a wide scope – it includes virtually all books cataloged before 1956.

Evaluation of NUC • Bibliographic Content: It is a massive bibliography alphabetized by author – everything is verifiable
