Old techniques in indexing, such as thesauri, can form the foundation of the most recent techniques. Examples include automatic indexing, ontologies and topic maps. Indexing describes the various traditional and new indexing techniques, providing information professionals and students of library and information sciences with a broad and comprehensible introduction to indexing.
