"This library is a congressionally designated depository for U.S. Government documents. Public access to the government documents collection is guaranteed by public law. (Title 44 United States Code)"
Columbia University has been a depository for Federal documents since 1882. There is no separate U.S. Government Documents collection in the Columbia University Libraries. CLIO has records for most U.S. government depository titles, indicating the location in one of the campus libraries, according to subject. Some materials (primarily pre-1976 Congressional documents) still can only be identified and located through the card catalogs in the Butler Library Reference Department.
Most print documents published since 1976 are now located in the Offsite storage facility. The CLIO records will indicate this location and provide a means for recalling the items from off-site on request.
