Unit 11: Chain Procedure

Postulate-based Permuted Subject Index (POPSI), designed by Ganesh Bhattacharyya at Notes
the Documentation Research and Training Centre (DRTC), Bangalore, is another indigenous
indexing model besides Ranganathan’s Chain Procedure.
POPSI is not based upon any particular system of classification but built around a set of
fundamental theoretical ideas on classification both in the analysis of subjects as well as in
the structuring of the names of subjects.
PRECIS (Preserved Context Index System) was designed and developed by Derek Austin
by about 1970 as an alternative procedure for deriving the subject headings and subject
index entries for British National Bibliography (BNB).

The formation of subject headings in PRECIS is done in two stages.
PRECIS is considered to be the first computerized pre-coordinate indexing model.
