n.A system of generating complex, coordinated access points for subject indexing.


PRECIS is a contraction of PREserved Context Information System.


Lancaster 1998, p. 56 In PRECIS, computer programs generate a complete set of index entries and cross references for an item from a string of terms and instruction codes provided by an indexer. The subject matter of a document is described as a series of terms that are put in a context-dependent sequence. . . . Each term is essentially dependent on the term immediately before it.
