External services in retrospective searching

Abstract

For this paper external services are defined as intermediaries between the original publication and its subsequent retrieval in response to an enquiry. Thus they include periodic indexes produced by publishers, abstract journals, indexes (or abstracts) sold in computer‐readable form, and organizations offering search services who may, themselves, use any of the foregoing.
