Superintendent of Documents Classification System (SUDOC)
As a Federal Depository Library, Randall Library receives many publications issued by agencies of the U.S. Government. These publications, which may include books, maps, posters, pamphlets, and periodicals, contain information on careers, business opportunities, space exploration, health and nutrition, energy, and many other subjects.
Federal Government publications in this collection are arranged by the Superintendent of Documents classification number. Publications are grouped together by issuing agency. To ensure that you find all of the materials available on a particular subject, be sure to check the indexes recommended by library staff. Some materials are distributed to Depository Libraries in formats other than paper, i.e., microfiche, or CD-ROM.
The example below shows how the Superintendent of Documents classification number C 61.34:987 is constructed for the publication U.S. Industrial Outlook:
