Question/Answer

What is a Superintendent of Documents (SuDocs) and how do I read the number?

Superintendent of Documents Classification, commonly called  SuDocs or SuDoc, is a library classification system developed and maintained by the United States Government Publishing Office. Unlike Library of Congress Classification, Dewey Decimal Classification, or Universal Decimal Classification, SuDocs is not a universal system. Rather, it is intended for use only in the United States federal government publications. Also, SuDocs does not organize materials by subject but by the agency that created those materials, making it a provenance-based or archival classification system.

SuDocs call numbers are assigned by the Government Publishing Office as new publications are produced. Many  Federal Depository Library Program libraries employ SuDocs to classify their collections.
