IMC Journal, the official publication of the International Micrographic Congress, has published a guide to portable microform readers in its Third Quarter, 1982 issue. Some 26 machines are pictured and described. Unfortunately price information is not included. Nevertheless, it provides a useful overview covering units ranging from large, briefcase models with screens up to 11" x 17" to hand-held ambient light viewers which can fit into a shirt pocket. Both film and Fiche readers are described. The full citation is: Exelbert, Rodd S., "A Guide to Portable Readers," IMC Journal, Third Quarter, 1982, pp. 11-15.
