- Abstract
- This 5th ed. has been heavily revised and partly rewritten. It comprises 5 parts: (1) Theory of information retrieval systems (covering derived indexing, printed indexes and database access systems as well as sematics and syntax); (2) Precoordinate indexing systems (covering subject headings, notation, alphabetical index, OPACs); (3) Precoordinate indexing languages (covering the DDC, UDC, BC, CC, LCC, LCSH and shorter lists of subject headings); (4) Postcoordinate indexing languages; (5) The future (digital libraries).
