SuDoc Classification System

The SuDocs (Superintendent of Documents) system organizes publications based upon issuing agency.  The SuDoc number or call number is based on this issuing agency.           A = publications of the Department of Agriculture,  C = publications of the Department of  Commerce, D = publications of the Department of Defense, HS = publications of the Department of Homeland Security, and so on.

There are exceptions:  Y 1 call numbers are general publications of Congress such as House and Senate Documents and Reports;    Y 3 call numbers are publications of  independent boards and commissions of Congress; and Y 4 call numbers are House and Senate Committee hearings and publications.

The SuDoc system is not a decimal system.  The number after the point is a whole number.

                  i.e. - in order --- A 1.2,   A 1.23,   A 1.256

If the call number is the same to a certain point, then varies, the order is: Years, Letters, Numbers. Until the year 2000, the first number was dropped from years, so those years have 3 digits. Beginning with the year 2000, years will be 4 digits. 

                 i.e. - in order ---   A 1.2:999   A 1.2:D 600,   A 1.2:90-2

The call number stem is the numbers before the colon.  If this stem has numbers slashed onto the base number, the base number comes first, followed by the slashed numbers in order.  (A 1.23:   is the base number)

               i.e. - in order --- A 1.23:     A 1.23/D:     A 1.23/D-2:    A 1.23/2



    Citing Government Documents

    Search for government publications

     All Rowan depository print publications received between 2010 and 2015 have been cataloged and may be found by searching the library's online catalog (author, title, or keyword).

    Government Documents are the publications put out by government agencies – federal, state, local, and international. They do not deal solely with law and politics, but are reports on every aspect of life whether involving current events, education, science, technology, sociology, medical, etc. They are often the best, and sometimes the only source of statistical information on a given topic.

    Most recently published government documents are available on the internet. However, many important documents are still only available in other formats, such as books, periodicals, pamphlets, posters, maps, and video (either DVD or VHS). Not everything can be found using a Web search engine.

    Public access to government documents is guaranteed by law and is your right as a citizen.

    Brief History of GPO and FDLP

    In the Act of 1813, Congress first authorized legislation to provide for the distribution of   one copy of the House and Senate Journals and other Congressional documents to certain universities, historical societies, state libraries, etc.  


    In 1857, the Secretary of the Interior began to oversee government printing and the designation of depositories that would receive these publications or documents. By a joint resolution of Congress in 1858, each representative could designate a depository from his district as well as the delegates from each territory. In 1859, each Senator gained the authority to designate one depository in his state.


    In 1860, GPO (The Government Printing Office) was established in order to consolidate Congressional printing. Prior to that date, printing had been handled entirely by private firms.


    In 1869, an appropriations act established a Superintendent of Public Printing within the Department of the Interior. This position was the forerunner of the current Superintendent of Documents.   An 1876 law changed the title of the "Superintendent of Public Printing" to "Public Printer" and the office became a presidential appointed position, subject to Senate confirmation. Davita Vance-Cooks was approved by the U.S. Senate to become the 27th Public Printer of the United States on August 2, 2013.  She is the first African American and the first woman to be nominated and confirmed for the leadership of the GPO.


    The Printing Act of 1895, the direct antecedent of Title 44, United States Code, collected and organized all of the extant printing laws.


    In 1895, when Congress established the office of Superintendent of Documents within the Government Printing Office, the Superintendent became responsible for the sale and depository library distribution of Government publications. In 1895 there were 420 depository libraries.


    Between 1895 and 1903 the Superintendent of Document (SuDocs) classification system was developed by GPO Librarian Adelaide Hasse. Based on publishing agency, the SuDocs system still arranges documents in most depository collections today.


    Until 1922, every depository library had to receive every publication from the United States Government.  Changes to Title 44 in 1922 allowed libraries to become “a selective depository,” where the library does not need to receive all publications, but can select only the publications that they want to receive.  Campbell Library is a selective depository, receiving about 30% of what GPO distributes. 


    The Federal Depository Library Program (FDLP) distributes GPO’s publications although providing Government information to selective libraries antedates the founding of GPO.


    For the FDLP, the United States is divided into regions, generally by state, and each region has a regional depository that receives every publication from the United States and provides a variety of services to the selective depositories in their region.  In New Jersey, the regional depository is the Newark Public Library.


    In 1993, GPO Access was created, one of the first government information databases.  Since 1996, the United States has been moving to a more electronic Federal Depository Library Program.  GPO created a free online catalog of official government documents from 1976 to the present and has recently released the Federal Digital System (FDSys)

    which should grow into an even greater database of government publications for the 21st century.
