Government Documents: Classification Outline for Gov't Docs

This is a guide to government resources that are commonly used in research.

How Government Documents Are Classified

At CSU Libraries, the SuDoc (Superintendent of Documents) Classification System is used for the Government Document collection (print, microfiche, DVD, and online sources.)

In the SuDoc system, publications are grouped together by issuing agency. These 2 example shows how a classification number is constructed:

  • Title:  Occupational Outlook Handbook    SuDoc Number:   L 2.3/4:2006-07

           L   Labor Dept. (issuing agency)    2.   Bureau of Labor Statistics (subordinate bureau within the agency)     3/4:  no. designating the title     2006-07   year

  • Title:  International Energy Outlook with projections to...      SuDoc Number:  E 3.11/20-3:1999

           E  Energy Dept. (issuing agency)   3.  Energy Information Admin. (subordinate bureau within the agency)  11/20-3:  no. designating title     1999  year
