The physical arrangement of reading, storage, and service areas for the microform department of the Joseph Regenstein Library can serve as a case study for the estimation of space requirements for microform storage and retrieval. The library uses mechanical readers at carrel stations, each utilizing 31.5 square feet of floor space. The best methods for storing microforms employ specially constructed metal cabinets or shelves. Direct public access to microfiche collections is impractical, but in small collections it is possible to allow access to film. As collections grow large, it becomes economical to automate retrieval using self-contained or remote controlled equipment. (KB)
