"The Federal Depository Library Program (FDLP) was established by Congress to ensure that the American public has access to its Government's information. Since 1813, depository libraries have safeguarded the public's right to know by collecting, organizing, maintaining, preserving, and assisting users with information from the Federal Government. The FDLP provides Government information at no cost to designated depository libraries throughout the country and territories. These depository libraries, in turn, provide local, no-fee access to Government information in an impartial environment with professional assistance." (from FDLP Desktop)
Other depository libraries in San Diego include San Diego Public Library, San Diego State University, Cal State San Marcos, University of San Diego, and San Diego Law Library. Find more information about these libraries' FDLP collections.
Unlike most print resources in the library, which are classified with the Library of Congress call number system, government documents are arranged by the Superintendent of Documents (SuDocs) call number system. The SuDocs system is a provenance arrangement—publications are organized based on the issuing agency. So, A call numbers are for the Department of Agriculture, C is Commerce, D is Defense, and so on. There are, of course, exceptions to the straightforward letters: X and Y are used for various Congressional publications.
One of the most confusing aspects of SuDocs numbers for those new to them is that the number does not read as a decimal, the way LC numbers do. Instead, the numbers before and after the dot are whole numbers. So, while D 19.18 would come before D 19.3 in LC order (because it reads as 19.one eight), it comes after D 19.3 in SuDocs order (because it reads as 19.eighteen). See MSU's SuDocs Basics for more guidance.
A very basic break-down of a SuDocs number:
UCSD became a selective depository library for the 53rd California Congressional District in 1963. As a Federal Depository Library, we provide free access to and reference service for publications issued by the federal government.
The U.S. government issues a vast number of publications that reflect on almost all aspects of our daily lives, and UCSD selects those publications we believe to be of greatest use to our constituencies. UCSD currently receives 53% of the publications distributed through the Federal Depository Library Program, creating an interdisciplinary social science collection with an emphasis on U.S. demographics, public policy and legislation. These items come in various formats, including print volumes, microfiche, CD/DVD, and online.
Most of our government documents are located in the west wing of the main floor of Geisel Library. Some documents are currently housed offsite at the library annex, but may be requested for delivery to Geisel Library. Call numbers for government documents may be found by using the library catalog, and most items may be checked out.
Public access to documents received through the FDLP is guaranteed by U.S. law. Please see the Library's policies covering Visitor Services and User Conduct for general information or contact Kelly Smith, U.S. Government Information Librarian, with specific questions regarding the federal documents collection.
