In exchange for the free publications, depository libraries agree to make those publications freely available to the general public. There is typically at least one depository library in each Congressional district. The D.H. Hill Library has been a depository since 1932. The library's Unity Lab is situated between the two halves of the paper federal documents collection. Microfiche federal documents are housed in the Microforms Room in the east end of the second floor of the East Wing of the library complex.
Maps are on the main floor, again in the east end of the East Wing.
A few CD-Rom products have been networked and are available on the library's information system. The Reference Desk is the place to come if you have questions about using the documents collection.
