This work tackles one of the fundamental problems of information management - how to get the right information to the right person at the right time. It provides a practical framework to enable information services to gather information from users in order to aid information system design, and to monitor the effectiveness of an information service. This new edition has been fully revised and now has increased coverage of the Internet. The Web raises many problems when it comes to meeting information needs - authority and overload, for example - and these problems make an effective information needs analysis even more crucial. There is a new methodology section on Web log analysis and focus group interviews. Practical advice is given concerning interview technique and an interview schedule is included.
