Microforms are printed or graphic materials that have been photographed and reduced in size. Included in the microform collection are materials in microfilm, microfiche, microcard, and microprint (defined below).
All titles which are cataloged are filed by call number. Uncatalogued sets are filed alphabetically or by a special accession number. Descriptions, filing arrangements and availability of indexes to special sets are listed in the "Microforms Collections Guide" (two notebooks kept on top of the Kardex).
Microform readers are available for all formats. Print and multiple-format digital copies can be made at each station.
The bulk of the collection is located on the first floor of McKeldin Library, in the Periodicals/Microforms Room. Government Documents and East Asia also maintain microforms dealing with their subject areas, as do the Architecture and Performing Arts Libraries.
Microfilm is transparent film on a reel. It comes in various sizes measured in millimeters.
Microfiche is transparent 3x5 or 4 1/2 x 6 film on a flat card.
Microcards are 3x5 reduced print, non-transparent microforms.
Microprint are 5x8 reduced print, non-transparent microforms.
