Abstract
Discusses the origins of hybrid classification systems, what characteristics these systems have or should have, and the advantages and disadvantages of such systems over other classification or indexing systems. The structure of technological information in patents and the basic pattern of description therein is reviewed briefly, and the document classification and indexing component of hybrid systems analysed.
