The United States Government is the largest publisher in the world. It distributes materials in a variety of formats, including electronic, CD, microfiche, and paper. As part of its publishing program, the U.S. Government Publishing Office (GPO) through the Federal Depository Library Program (FDLP) distributes certain classes of Government documents free of cost to designated libraries throughout the United States and its territories.These libraries are known as Federal depository libraries.
Federal depository libraries offer free, public access to their Federal collections. The CSU-Pueblo University Library is proud to be a Federal depository library.
All SuDoc numbers have the same structure: STEM : SUFFIX. SuDoc numbers organize materials by the publishing agency. Usually, but not always, the name of the agency forms the first letter(s) of the STEM. Below are the most common SuDoc classes:
|A||Dept. of Agriculture|
|C||Dept. of Commerce|
|E||Dept. of Energy|
|ED||Dept. of Education|
|EP||Environmental Protection Agency|
|L||Dept. of Labor|
|S||Dept. of State|
