No matter what library you visit, all library materials are shelved by call number. The main call number system Oklahoma State University Library uses is the Dewey Decimal Classification ("Dewey") system. Both an explanation of how the Dewey system works and a summary of the Dewey numbers are available on the Web.

Besides Dewey, the OSU Library also uses SuDocs and Jackson Numbers in the Government Documents department. Other systems are used in Room 105 (Microform & Media Room) and Special Collections & University Archives.

To find OSU Library materials, check the Location in the online catalog record. For Main Library locations, the first part of the call number and the chart below indicate the floor where the call number is shelved. All other locations are listed below.
