United States Government Information can provide you with a wealth of information to help support your research paper or projects. U.S. Government documents are primary sources of information from the executive, legislative and judicial branches of the Federal Government.
SuDoc stands for Superintendent of Documents Classification System. A SuDoc number is a call number much like that of a library's call number. The government uses this system to organize and shelve documents by the SuDoc number. Sudoc numbers are made of two parts - the class stem and the book number.
