- Abstract
- Computer have been used in 2 areas of printed index production: to sort entries and fromat printed indexes, and to derive a series of index entries from a minimum intellectual input. Computer indexing enables more indexing terms to be used as well as weighted terms, links and roles. Interest in automatic indexing peaked in the mid-1960s and has since declined. Interest in machine-aided indexing concentrates on using the computer for on-line display or for indexing by extraction. Computers have also made possible the implementation of retrieval systems without indexing-free text systems. Considers future prospects and needs
