Praise for .... "Highly recommended." --Robert M. Hayes, LIBRARY DIGEST "Jean Tague-Sutcliffe is one of the leading scholars and teachers in
information science, with a particular strength in bibliometrics, and has written an important monograph on measuring the performance of methods that provide information to users, with chapters describin how to measaure
user-record informativeness, aggregating these values, and evaluating information services. The book provides a sophisticated justification for tools and measures used to evaluate information-based systems, moving
beyond simple statistical techniques to take into account the variou sproblems and conditions that face information professionals managing information systems...It is a pleasure reading material that so clearly
addresses the problems of the field." --Robert Losee, University of North Carolina, in JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE Measuring information is a key part of evaluating
information services such as libraries, on-line 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. Dr. Tague-Sutcliffe was awarded the 1996 Award of Merit from the American Society of Information Science (ASIS) for her lifetime contributions to research and education in the field of information science.
Measuring Information
was also awarded the 1996 ASIS award for Best Information Science Book, based on its importance to information science and technology, readability, validity, originality, research significance and scholarship. KEY FEATURES
- Written by a recognized authority on theory and method of measurement in information science
- Provides the tools to evaluate the usefulness of information from libraries and information retrieval systems
- Illustrates techniques with examples and computer source codes
