If the public wants to borrow books they must ask their local library (i.e. public, school, university, or corporate library) to borrow them from the USGS Library via a process called interlibrary loan (ILL). Your local library may send ILL requests through either the OCLC electronic ILL system (see symbols below) or on the standard American Library Association (ALA) form by mail or FAX. The USGS Libraries will not accept requests by telephone or e-mail. Pre-approval by your local library is required before an individual may borrow a book in person but you must bring along one of the completed forms listed above.
