Title

Software for information storage and retrieval, evaluated and compared : pt.7: what to choose, or the purpose of it all

Abstract

The more than 3700 data presented in the tables of preceding articles in this series, pertaining 37 different software packages for information storage and retrieval (ISR), may seem overwhelming to the reader who needs to make a well-founded choice. To make this task easier, some general questions can be asked with respect to the desired ISR application. These questions can be summarised as: what sort of information? How much? For whom? For what purpose? At what cost? The discussion about user needs, typical applications and lists of demands centres around these five basic questions in relation to the categories of retrieval software which were identified in the six earlier articles. They cover the whole range from bibliographic software to advanced full-text retrieval software
