About the SUDOCS Cataloging System

As you work with Government Documents, you may notice that the call numbers assigned to the documents are completely different than the Library of Congress or Dewey Decimal System call numbers you may have encountered in the past. That is because Government Documents use the Superintendent of Documents (SUDOCS) numbering system. For more information on this unique numbering system, visit this  website.

Description of the Depository Library Program

Take a look at the logo to the left.  It is the symbol of the Federal Depository Library Program (FDLP) and it shows an eagle cradling a book in its wing.  This succinctly illustrates the FDLP's mission.

In the words of the U.S. Government Publishing Office (, which administers the FDLP, "The Federal Depository Library Program was established by Congress to ensure that the American public has access to its Government’s information. GPO administers the FDLP on behalf of the participating libraries and the public. Information products from the Federal Government are disseminated to these nationwide libraries that, in turn, ensure the American public has free access to the materials, both in print and online."
