Information retrieval is a commumcation process that links an information user or seeker to a computer system that contains data bases or to a librarian, museum curator, fingerprint identiflcation specialist, or whoever is in charge of a collection of what we are calling documents. The communication will normally involve the processing of text, strings of words known to both parties in the process that can be used to describe a document's content and other attributes and link it with a need expressed in similar terms. Even non-text entities, such as musical themes, are converted to alphanumeric symbols to allow effective storage, search, and retrieval. This book's purpose is to teach people who will be searching or designing text retneval systems how the systems work. For designers, it covers problems they will face and reviews currently available solutlons to provide a basis for more advanced study. For the searcher its purpose is to descnbe why such systems work as they do. The book as primanly about computer-based retneval systems, but the principles apply to nonmechanized ones as well.

The book covers the nature of information, how it is organized for use by a computer, how search functions are carried out, and some of the theory underlying these functions. As well, it dlscusses the interaction between user and system and how retrieved items, users, and complete systems are evaluated. A limited knowledge of mathematics and of computing is assumed.

The first edition of this work appeared just before the World Wide Web came on the scene, but was nonetheless a student favorite because of its clarity. The second edition was updated and expanded, covering not only the Web but also new developments in how information retrieval systems are or could be designed. The growth of the Web as an access mechanism to traditional information retrieval systems, and particularly the proliferatlon of search engines associated for Web searchmg, have led to this third edition.
