This will be the third edition of the highly successful "Text Information Retrieval Systems". The book's purpose is to teach people who will be searching or designing text retrieval systems how the systems work. For designers, it covers problems they will face and reviews currently available solutions to provide a basis for more advanced study. For the searcher its purpose is to describe why such systems work as they do. The book is primarily about computer-based retrieval 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 discusses 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. This third edition will be updated to include coverage of the WWW and current search engines. In many cases, examples of non-web searching will be replaced with web-based illustrations. Coverage of interfaces, various features available to assist searchers, and areas in which search assistance is not available will also be covered. In addition, the book will have a web dimension which will include relevant material available online, to be used in conjunction with the text. It is a follow-up to the award winning 2nd Edition. It focuses on computer-based system but basic principles can be applied to any information seeking context.

Meadow takes us on a Cook's tour of communication technologies across time_the alphabet and moveable type printing, cave drawings and carrier pigeons, telephones, television and, of course, the Internet. In each case, Meadow shows how these (and other devices) are connected to each other, even as they serve to make connections between people. Part One discusses the basics of communications, while Part Two delves into telecommunications before the days of steam and electricity. Part Three offers insight into steam, electricity, and internal combustion energy and how they revolutionized society. Communication is the key to a productive world. For those dazzled by the pace of change in the technology or McLuhan's unorthodox but brilliant insights, Meadow's casual style and pace provide the perfect antidote.

A deep and penetrating exploration of the key concepts of information and communications sciences by one of its founders, this book covers everything in its subject that you want to know more about including the bedrock topics of signs, symbols, information, and communication, all considered from an historical and foundational perspective that is satisfying to the beginning student and worthwhile for practitioners of long standing. All the major players are given their role, from Shannon and Weaver to Tim Berners-Lee, with Marshall McLuhan an engaging participant. Communication in all its forms—be it print or electronic media, mass communication as well as person-to-person messaging, whether by mail, telephone, gesture, or email—is thoroughly examined in this book, which can serve as either an introductory text to undergraduates in information science, an interesting read for the layman, or as a refresher for the communications professional.
