10.5 Summary

• A classification system is an established plan that divides all knowledge into precise catego-
ries and subcategories.
• Pre-coordinate indexing systems are conventional systems mostly found in printed indexes.
• Chain Indexing or chain procedure is a mechanical method to derive subject index entries or
subject headings from the Class Number of the document.
• In Chain Procedure the indexer or cataloguer is supposed to start from where the classifier
has left.
• Chain Indexing was originally intended for use with Colon Classification.
• POPSI made the indexing system free from classification scheme because this system is based
on general theory of classification and is not tagged with any classification scheme.
• PRECIS was intended to be a complete subject statement in a form suitable for a printed bib-
liography.
• COMPASS is a simplified restructuring of PRECIS.
• DDC number is also used as a source of feature heading.

• Post-coordinate indexing systems are used in combination with Boolean logic.
• “Coordinate indexing” as a concept and as a method is founded by Mortimer Taube in 1951.
• Citation indexing makes links between books and articles that were written in the past and
articles that make reference to (“cite”) these older publications.
