The USGS Library lends certain materials to the public and other libraries through interlibrary loan. The library will not process requests communicated by telephone. Pre-approval is required before an individual may pick up an interlibrary loan item in person. GIG The loan period for ILL is four weeks, with one renewal. Copies up to 10 pages may be supplied in response to an interlibrary loan request in lieu of lending the item.
Loans are free of charge.
