Government Information Services, Access, and Collections provides access to the largest and most comprehensive United States Federal Depository Library collection in east-central Illinois.

The University Library began collecting U.S. Federal documents of significant research value prior to becoming a depository in 1907, and therefore has a substantial collection of 19th century congressional materials, agency reports, and statistical series. We have received all State of Illinois materials, including documents from the Illinois General Assembly and other Illinois state agencies, from the 1950s forward.
