Hash coding of bibliographic data using techniques based on variety generation and on division

Abstract

The use of variety generation techniques in the production of author‐title search codes for files of monograph records is compared with methods based on division hashing. The latter perform better, and evidence is presented to suggest that the reason for this is the lack of statistical independence between the assignments of variety generation symbols to different parts of a field in the record.
