Brief History and Overview

Since 1895, the Carnegie Library of Pittsburgh (CLP) has been providing Pittsburgh and surrounding communities with free access to a wide variety of federal documents and information. Today CLP is part of a national network of approximately 1350 Federal Depository Libraries located throughout the United States and its territories. In Pennsylvania's 14th Congressional District (in which the City of Pittsburgh lies), CLP is one of only six official Federal Depository Libraries.

Although not a full depository (roughly 55% of the offered item numbers are currently received), CLP does select most of the standard titles recommended by the Federal Depository Library Program for depository libraries its size. These materials are distributed among the various Main Library departments with the greatest concentrations in Reference Services, which is also an official Patent and Trademark Depository Library.

Most government documents are now listed in THE CATALOG (Online). For a detailed search of documents beyond the library's collection, use the official Catalog of U.S. Government Publications (1994 to date), MarciveWeb DOCS Catalog (July 1976 to date), or the print version of the Catalog of U.S. Government Publications, MOCAT (1895 to date).
