Synopsis A number of organisations have produced, or are producing, packages of programmes usually written in a general way for library and information work. Details of packages suitable for particular applications will be described in the relevant chapters, and points to consider when choosing software are described. In this book some of the packages which have been developed as integrated library systems will be described in detail as these encompass applications; some of these have been developed mainly for one library or group of libraries but are capable of being used by the other libraries.
