API patent abstracting and indexing -- Cooperative efforts in historical perspective

E.H. Brenner

World Patent Information, 1987, vol. 9, issue 1, 27-33

Abstract: The article describes the cooperative efforts of American petroleum companies which led first to the initiation in 1954 of the Central Abstracting and Indexing Service (CAIS) of the API and subsequent cooperation with Derwent in producing in 1972 the API Patent Alert Abstracts Service covering selected chemicals and polymer patents. The API alerting bulletins contain about 25 000 abstracts of which CAIS indexes only about 8000 under their indexing selectivity rules. The cooperation has made possible the construction of high quality indexing of abstracts covering the petroleum processing and product patents. The development of the API indexing philosophy, based on keywords and terms, is described along with future developments aimed at automatic indexing.
