Many of the government publications received in the law library are shelved in the general collections on the 6th, 7th, and 8th floors according to the Library of Congress classification numbers. Other federal documents are shelved on the 9th floor in the Superintendent of Documents collection or in the Superintendent of Documents microfiche collection on the 8th floor.

The Superintendent of Documents (SuDocs) classification number is used as a call number in the law library's Superintendent of Documents paper and microfiche collections. The SuDocs number is alphanumeric and describes the publication.

To locate a particular government publication, first use BEN. BEN will identify all documents shelved in the general collections and many of the documents shelved and filed in the Superintendent of Documents collections. BEN can be searched by keywords in the title or author's name, author, title, subject, classification number (Library of Congress), or government document (SuDocs) number.

The most comprehensive search may be a word search. Key the distinctive words of the name of the department/agency, Congressional committee, or court. For example, to retrieve the Administrative Decisions of the Board of Immigration Appeals, select keyword from the menu then key immigration decisions. To retrieve the catalog information for Senate Treaty Documents, key senate treaty document*. To find hearings from the House Committee on Aging, key hearing* aging.
 
To search for publications authored by the U.S. Atomic Energy Commission, select author from the menu and key u.s. atomic energy commission.
 
To search by a Superintendent of Documents (SuDocs) classification number, select government document (gov't doc). Then key the alphanumeric number. For example, to identify Senate Treaty Documents, key in Y 1.1/4. To search for House Reports, key Y 1.1/8. To search for Senate Documents, key Y 1.1/3.
 
If the publication is not found in the online catalog, and the publication is a Congressional hearing, report, document, or print, use the various CIS indexes to identify the number under which the publication is shelved or filed. If the publication is issued by the executive branch, use the Catalog of U.S. Publications, Andriot's Guide to U.S. Government Publications, or Popular Names of U.S. Government Reports to identify the material.
