Abstract
Presents a state of the art review of current awareness services in 1997 noting: the components of typical current awareness services; the range and types of databases that may be scanned during searches; and the role of feedback and document delivery mechanisms. Includes a checklist of criteria which may be used to evaluate current awreness services, including: database coverage; timeliness and currency; cost; and mechansims for creating and maintaining user SDI profiles. Discusses the main types of current awareness services: contents page services; abstracting and indexing services; and integrated online products (such as Engineering Index's Engineering Village), including SDI. Considers the concept of currency and remarks on the tendency for current awareness services to be products of a producer led rather than a user led culture
