Finding Congressional Hearings


1. Use the library catalog to identify the hearing’s call number—it will begin with Y4—and the Congress in which it took place. Hearing dates indicate the Congress. Congressional publications are organized by Congress and then call number. There are charts posted in the Y4 area on the 4th floor to help people convert dates to Congresses and find materials.



1887-1889 50th Congress
1987-1988 100th Congress
2005-2006 109th Congress

2. Locate the appropriate Congress (e.g., 109th Congress) within the Y4 area of the government documents stacks in compact shelving on the 4th Floor.

3. Within the appropriate Congress, search for the hearing by call number.

SuDoc Call Numbers

Government publications use a unique call number system called the Superintendent of Documents (SuDoc) system. In the Libraries’ Catalog, the SuDoc number will be listed next to the material’s location:


Y 4.EN 2:S.HRG. 105-15

In the SuDoc system, government publications are grouped together by issuing agency rather than subject, so all publications from a particular government department or agency are shelved together. To learn more about the SuDoc call number system, click here.
