SuDocs (Government Documents) Call Number Locations

Most U.S. government publications are classified in the Superintendent of Documents (SuDoc) classification. The call number is not based on subject, but on the Federal agency that issued the publication and the type of publication. The most important thing to note is that the dot in the call number is NOT A DECIMAL, but a whole number. For example: call numbers beginning with HE 20.2: come before HE 20.11. HE 20.11, in turn, precedes HE 20.101: which precedes HE 20.1001: Alphanumeric combinations, however, are decimals, though they have no decimal point, e.g., A76 precedes A8.

For help locating government documents, see a Reference Librarian.
