Understanding Government Document Call Numbers

Library call numbers which begin with the prefix "US" indicate a United States federal government document. These documents use a different call number system than the regular book collections at the UB Libraries. The Superintendent of Documents ("SuDocs") Classification System groups federal documents by the government department or agency that produced them. Each department and agency is assigned a unique letter code. The table below contains examples of selected departments and agencies whose documents may be found in the UB Libraries.

The remaining letters and numbers in a SuDocs call number contain additional information which will be necessary to locate the document on the library shelf, including the subordinate office and type of publication. It is important to note the entire SuDocs call number before attempting to locate a federal government document on the shelf in the UB Libraries.
