Most of the collection at CSU-Pueblo Library uses the Library of Congress Classification system as it's organizational scheme. However, the Government Documents area of the collection uses another system to organize materials. The Superintendent of Documents (SuDoc) Classification System was developed by the United States Government Printing Office specifically to organize government documents. Whereas the LC classification system organizes items by subject area the SuDoc system instead organizes items by the government department and agency that created them. Use the information on this page to explore more about SuDoc and how to understand it.
Michigan State University and the American Library Association's Government Documents Round Table worked together to produce a valuable tutorial for library student workers and staff. Please explore the links below to learn more about SuDoc numbering and try out your knowledge.
