First steps in choosing information retrieval packages Available to Purchase

Microcomputers offer a new scope and a new challenge to libraries and information units. For many, computerisation of procedures is at last within budgetary restrictions and the possibility of providing new services through the use of the microcomputer is a strong incentive to buy.

Self help is the only realistic option for many libraries. This article is intended to give useful background information and to help structure ideas before the business of selecting a suitable information retrieval (IR) package is begun. This is an introductory article intending to outline basic concepts.
