Indexing Aids, Procedures and Devices

摘要

The purpose of this study was to analyze proposed and available techniques and devices designed as aids to the manual indexing operation in order to identify those manual and semi-automatic techniques and devices which increase the speed, accuracy, and consistency of indexers. Three modes of data collection were used: (1) Review of the Literature, (2) Visits to pertinent facilities, and (3) A mail survey of relevent technical information agencies and private manufacturers. The major results of this study were: (1) Eight classes of indexing aids were identified and are discussed in detail with regard to their rationale, development, and application. (2) Little experimental or objective data are available regarding the development or effectiveness of indexing aids. (3) No mechanical devices were identified which were specifically designed as aids to the manual indexing operation. The results of this study indicate that if the manual indexing process is to be optimized, a greater effort must be expended in the direction of objectively and quantitatively studying the indexer, the indexing operation, and the techniques for improving indexer performance.
