Microform Microform is an invaluable means of storing and making available material that is bulky and will receive relatively low use, that will deteriorate rapidly, or that is rare, expensive, or otherwise unavailable.
Examples are newspapers and the American Cultural Series.
Microform is normally avoided for material that is expected to receive heavy use. Printed copies of materials we hold on microform should not be ordered unless heavy use is anticipated or some special feature that the film does not provide, such as color illustrations, is needed. The library collects only those maps placed on deposit by U.S. Defense Mapping Agency. U.S.G.S. quads are maintained in the Geology Department. Statements regarding the collecting of other materials will be developed at such time as the library begins collecting them.
