Overview

The expression "information retrieval" is generally used to describe the processes of searching for and finding information in a file or database by use of a computer. This is true even though the processes of searching and retrieving were performed long before computers were invented and may still be performed without them. But computers have greater capability and interest. They offer access to more and larger databases than ever before. Computers require that users learn new skills, and computers promise (but do not always deliver) far more satisfactory results than are attainable without them. This book provides a comprehensive treatment of information retrieval covering all aspects of this complex field, while emphasizing operational systems, rather than research, and the interrelationships among the users, the mechanical information retrieval system, and the databases.
