." . . a surprisingly useful and largely readable effort. It presents in textbook style an introduction to the creation, use, and evaluation of online full text databases." SLA SSD Bulletin Comprehensive and up-to-date, this book incorporates an overview of the current status of full text databases with explanations of past research pertinent to full text and information regarding the future of full text. The major online systems that offer full text are described, with five systems highlighted: DIALOG, Mead Data Central's LEXIS and NEXIS, Westlaw, STN International, and BRS. The book features an extensive bibliography that includes articles specifically about full text databases as well as citations to research studies that use methodology particularly appropriate to full text research.

This invaluable work provides a single-volume introduction to the principles, strategies and practices currently applied by librarians and recordkeepers to the preservation of digital information and will assist them to make informed decisions about the role of digital information in their care. The book is presented in four parts: Why do we preserve? What do we preserve? How do we preserve? and How do we manage digital preservation? Each part covers the area in detail and addresses current issues in a clear and informative manner. The terminology of the field is explained clearly throughout the book. Each chapter includes a range of case studies from institutionsat the forefront of digital object preservation. An index facilitates quick access. This book will be essential as a professional reference tool for all librarians, recordkeepers and archivists with preservation responsibilities as well as being a definitive source of information for the whole profession including students.

Text Retrieval and Filtering: Analytical Models of Performance is the first book that addresses the problem of analytically computing the performance of retrieval and filtering systems. The book describes means by which retrieval may be studied analytically, allowing one to describe current performance, predict future performance, and to understand why systems perform as they do. The focus is on retrieving and filtering natural language text, with material addressing retrieval performance for the simple case of queries with a single term, the more complex case with multiple terms, both with term independence and term dependence, and for the use of grammatical information to improve performance. Unambiguous statements of the conditions under which one method or system will be more effective than another are developed. Text Retrieval and Filtering: Analytical Models of Performance focuses on the performance of systems that retrieve natural language text, considering full sentences as well as phrases and individual words. The last chapter explicitly addresses how grammatical constructs and methods may be studied in the context of retrieval or filtering system performance. The book builds toward solving this problem, although the material in earlier chapters is as useful to those addressing non-linguistic, statistical concerns as it is to linguists. Those interested in grammatical information should be cautioned to carefully examine earlier chapters, especially Chapters 7 and 8, which discuss purely statistical relationships between terms, before moving on to Chapter 10, which explicitly addresses linguistic issues. Text Retrieval and Filtering: Analytical Models of Performance is suitable as a secondary text for a graduate level course on Information Retrieval or Linguistics, and as a reference for researchers and practitioners in industry.
