Abstract
Describes the online end user search service, FirstSearch, provided by OCLC, noting the ways it has developed since its launch in 1991, and the extent of its use in libraries worldwide. Focuses on an important new aspect of the service, the availability of the full text in ASCII format of many of the articles cited in the database, for ordering, viewing and downloading. Also discusses the value of FirstSearch to interloans departments, the costs of the service, enhancements in the searchability of the databases and in the interfaces provided for searching, and the variety of uses to which libraries are putting the service
