At WSU Libraries the SuDoc (Superintendent of Documents) Classification System is used for the tangible collection (print, microfiche, DVD, etc.) in Holland and Terrell Libraries and the Owen Science and Engineering Library. Other campus libraries have a small number of federal documents, classified in the Library of Congress system.
In the SuDoc system, publications are grouped together by issuing agency. These two example shows how a classification number is constructed:
L Labor Dept. (issuing agency) 2. Bureau of Labor Statistics (subordinate bureau within the agency) 3/4: no. designating the title 2006-07 year
E Energy Dept. (issuing agency) 3. Energy Information Admin. (subordinate bureau within the agency) 11/20-3: no. designating title 1999 year
