Compression of Bibliographic Data Bases Using a Variable to Fixed‐length Bit‐string Coding Transformation

Abstract

The application of a variable to fixed‐length compression coding technique to two bibliographic data bases (MARC and INSPEC) is described. By appropriate transformation of characters or digrams into bit patterns reflecting more accurately the distributions of characters in the data bases, and application of the encoding process, varying degrees of compression can be obtained.
