How to Use the SuDoc Call Number System

Federal documents are arranged on the shelves using the Superintendent of Documents Classification System (SuDoc). This system organizes materials by agency, rather than subject as with the Library of Congress system.

The first part of the number is a letter that identifies the department, commission or agency that issued the publication.

A = Agriculture

C = U.S. Census Bureau

I = Department of Interior

The numbers that follow indicate the sub-agency, such as the National Parks Bureau. For example:

I 29.9/5:156

I = Dept. of Interior, 29 = National Parks Bureau 

The numbers that follow indicate the type of publication and a final number unique to that publication. The letter X and Y refer to Congress. For example: A Congressional hearing referring to Homeland Security

Y 4.H 75:109-36

Y = Congress 

4 = Hearing

H = Homeland Security

These are the basic rules for finding documents on the shelf. If you have trouble finding a document, ask for help in the Government Documents Office.
