 Understanding Call Numbers in the Census & Data Room

Census resources in print are organized by a call numbers are issued by the United States Government Printing called SuDoc (which stands for Superintendent of Documents).  

Unlike other items in the library that are grouped by subject, SuDocs are grouped by the government agency that printed the document.  For instance, documents published by the Department of Agriculture begin with A, those published by the Department of Defense begin with D, those published by the Department of Justice begin with J, etc...  The numbers that directly follow  these letters (before the  decimal point) represent the specific office of a particular department.

For example, the call number C 3.134/2:C83/2/947 can be broken down as follows: 

SuDocs Call Number
Issuing Department C Commerce Department
Subagency 3 Bureau of the Census
Series 134/2 : Statistical Abstract Supplement
Title and date C 83/2/947 County and City Data Book, 1947
