Creation of Computer Input in an Expanded Character Set

Abstract

Keypunching of an expanded character set for library catalog data is described. The set included 101 different characters. Source documents were shelf list cards, the master record at the University of California Library, Santa Cruz. At the end of February 1967, some 50 million characters, representing more than 110,000 separate titles, had been punched. Some of the considerations leading to the adoption of this method for the creation of machine readable input are given, and details on costs and production rates.
