What are SuDocs

The Superintendent of Documents (SuDocs) system is the classification system EKU Libraries and the United States government use to identify and catalog government publications.

It was created over 90 years ago by the Government Printing Office (GPO) to essentially serve as the government's own system of call numbers

The Government Documents section is located on the 3rd floor of the Main Library

SuDoc Formatting

The format of a SuDoc number is as follows:

Department [Letter(s)] Agency # Series #

For example: NAS 1.26 indicates a NASA series, Contractor Reports. Or, I is for the Department of the Interior, 19 is for the U.S. Geological Survey and 42 is the number of the USGS series, Water Resources Investigations Report.
