Department of the Interior employees may borrow materials for four weeks. Register at the Library Reference Desk to establish borrowing privileges. Borrowers may call (202) 208-5815 to renew materials if no one else has requested them. Failure to return or renew items within the allotted time may affect borrowing privileges.
Departmental employees located outside the Washington Metropolitan Area may also request items from the collections. Please contact the Reference Desk by phone at (202) 208-5815 for more information on registering for borrowing privileges. Employees with access to a bureau or field office library must use their library's interlibrary loan services.
Some items in the collections may not be checked out. These include reference materials, copies of Departmental documents (D), items in the Law collection, volumes within the U.S. Congressional Serial Set, Department of the Interior appropriations hearings, journals, microforms, CD-ROM and DVD-ROM products, and books housed in the Rare Books Collection. When possible, photocopies may be made of these materials. Copyright restrictions apply to all photocopies.
