Book Description
This title is part of UC Press's Voices Revived program, which commemorates University of California Press’s mission to seek out and cultivate the brightest minds and give them voice, reach, and impact. Drawing on a backlist dating to 1893, Voices Revived makes high-quality, peer-reviewed scholarship accessible once again using print-on-demand technology. This title was originally published in 1981.

Book Description
Published in 1992, like the first, this second edition is not intended as introductory textbook command-driven, Boolean searching. It is targeted at online searchers who already have some knowledge of command languages and may be proficient searchers on databases in one or two subject areas, but when required to venture into new and less familiar territory still need guidance. It is also offered to end users who possess the subject expertise but lack of information retrieval know-how. The Manual is offered as a guide to database selection and a navigational aid through the twists and turns of the retrieval maze; at least some of the dead ends and backtracking may thereby be avoided. This volume, written by experts in their various fields, deals with the subject coverage and record structures of specific databases, offers comparisons between databases (context, indexing procedures, updating policies, etc.), discusses the choice between online and CD-ROM sources (and between hosts if online is selected), and illustrates strategies with numerous search extracts.

Book Description
Chapter 1 places into perspective a total Information Storage and Retrieval System. This perspective introduces new challenges to the problems that need to be theoretically addressed and commercially implemented. Ten years ago commercial implementation of the algorithms being developed was not realistic, allowing theoreticians to limit their focus to very specific areas. Bounding a problem is still essential in deriving theoretical results. But the commercialization and insertion of this technology into systems like the Internet that are widely being used changes the way problems are bounded. From a theoretical perspective, efficient scalability of algorithms to systems with gigabytes and terabytes of data, operating with minimal user search statement information, and making maximum use of all functional aspects of an information system need to be considered. The dissemination systems using persistent indexes or mail files to modify ranking algorithms and combining the search of structured information fields and free text into a consolidated weighted output are examples of potential new areas of investigation. The best way for the theoretician or the commercial developer to understand the importance of problems to be solved is to place them in the context of a total vision of a complete system. Understanding the differences between Digital Libraries and Information Retrieval Systems will add an additional dimension to the potential future development of systems. The collaborative aspects of digital libraries can be viewed as a new source of information that dynamically could interact with information retrieval techniques.
