Abstract

Medline is the computer searchable version of the US National Library of Medicine's Index Medicus and has evolved from the Medlars project of the mid 1960s. Medline files can be subdivided into 3 major groups: Full Medline, Short Medline and Specialist Medline. A small number of products are targeted more individual end users rather than the normal library/information service market. Search software is now largely concentrated on Dialog OnDisc, BRS Search and SilverPlatter's SPIRS software
