Abstract
Abstract The specific information storage and retrieval system described herein stores 49,000 microfiches in a central file, any one of which may be viewed in a matter of seconds. More specifically, the central file uses an arrangement of 20 shelves mounted on a closed loop track, each holding 2,450 microfiches, each microfiche in turn having 50 or 60 separate images. When a particular microfiche is selected, the proper shelf is rotated into a predetermined position. Concurrently a viewing station including a transducer such as a film camera or a television camera is brought adjacent to the selected microfiche which is partially extracted from its storage location so as to be viewed by the transducer.
