An overview of the OPTIRAM/LIBPAC computerised system for the intelligent optical scanning of catalogue cards, or any other form of printed or good hand‐written material, into a full MARC format is given. The article provides information on the sophisticated scanning technology employed, using standard Group 3 facsimile transmission devices to read catalogue card entries and produce an internally coded data string, used to drive format recognition programs developed by LIBPAC, each tailored to suit a particular application. Sections deal with the varied aspects of this individual approach and the benefits that can arise from taking advantage of user‐specific software to enhance and standardise the resulting machine‐readable catalogue. The article includes examples which show the full capabilities of the optical scanner and examples of catalogue cards that have been converted into the MARC format.
