Finding Materials in the Stacks

Overview

Most U.S. government publications are classified in the Superintendent of Documents (SuDoc) classification. The call number is not based on subject, but on the Federal agency that issued the publication and the type of publication.

Reading SuDocs Numbers

The most important thing to note is that the dot in the call number is not a decimal, so the numbers that follow are whole numbers.  (HE 20.2 comes before HE 20.11 ; HE 20.11 comes before HE 20.101)‚Äč 

Alphanumeric combinations are read as decimals, though they have no decimal point. (A76 comes before A8.)

The U.S. Industrial Outlook has the SuDoc number: C 61.34:994
