U.S. GOVERNMENT INFORMATION RESEARCH GUIDE: About Depository #635

The best way to find the location of a government document is to search for it in OneSearch.

• Newer print documents -- those received since 2010 -- are interspersed with the rest of the collection, which is arranged by Library of Congress (LC) call number. 
• Microforms are located in cabinets on the B2 Level in the Microforms Area.
• CD-ROMs are also located in cabinets on the B2 Level in the Microforms Area.
• Maps are on the B2 Level at the far end of the B2 Annex (far left on the map of the floor).

U.S. Government Documents have their own classification system, in which the Government Publishing Organization assigns a "SuDoc" number to each publication (The term SuDoc refers to the Superintendent of Documents, the head of GPO). This system classifies each document by the agency or department that issues the document instead of by subject. For example, SuDoc classification A is for materials issued by the Agriculture Department. That means it doesn't make sense to browse the government documents collection (the way you might in the rest of the library) since many agencies/departments issue documents on similar subjects.

Quick Tips:

• The dot (.) is a period, not a decimal.
• All numbers are whole numbers, not decimals (.9 comes before .12).
• Letters come before numbers.
• Nothing comes before something (for ex. AE 1.102 : G 28 precedes AE 1.102 : G 28/2/Trans.7).
