Backfile conversion today: CIM era or chimera?
John Ross, Bruce Royan · Data Technologies and Applications · 1977
The difficulties of retrospective library catalogue conversion are described. Computer Input Microfilm (CIM) is compared with more conventional Optical Character Recognition (OCR) techniques. After giving examples of known uses of the technique, and listing studies of it in a library context, the paper outlines the scope for such a system within a very large library such as the British Library.
