Measuring information is a key part of evaluating information services such as libraries, online services, information centers in organizations, and more. Measuring Information: An Information Services Perspective presents a new user-centered measure of information and describes how to use this method to evaluate information services of all kinds, especially library acquisitions. The book uses the mathematical theory of measurement to derive this measure.

It shows how it can be applied to a number of evaluation problems relating to overall services and a choice of databases, collection policies, classification schemes, retention schedules, indexing, languages, search strategies, and information packaging in information service agencies.
