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.

Comprehensively updated, this three-volume edition of the Manual of Online Search Strategies covers the whole range of Internet, CD-ROM and dial-up online services, and includes several new chapters. International experts on each subject area, selected from the UK and North America, describe in detail how to identify and exploit specialist bibliographic and non-bibliographic databases, the best search methods and delivery modes, and the relative merits of different services and online hosts in their different disciplines. Numerous examples of search results are used to illustrate different strategies and commands.Each volume includes the editors' introductory chapter on search strategies, which gives an overview of searching language, platforms and vendors, interfaces and search and database evaluation methods. This volume includes the new chapter on earth sciences, while engineering and energy-related sources are now covered in one combined chapter. Other chapters have been fully revised.The Manual can be used as a subject handbook, a directory of recommended resources and as a textbook. This new edition provides extensive guidance for searchers of electronic information and is particularly useful for those working in a subject area other than their own. Readers will gain a professional 'edge' from the skill and wisdom that the specialist authors have passed on in their chapters and will be able to expand their searching techniques into new areas.

Updates the premier textbook for students and librarians needing to know the landscape of current databases and how to search them. Librarians need to know of existing databases, and they must be able to teach search capabilities and strategies to library users. This practical guide introduces librarians to a broad spectrum of fee-based and freely available databases and explains how to teach them. The updated 6th edition of this well-regarded text covers new databases on the market as well as updates to older databases. It also explains underlying information structures and demonstrates how to search most effectively. It introduces readers to several recent changes, such as the move away from metadata-based indexing to full text indexing by vendors covering newspaper content. Business databases receive greater emphasis. As in the previous editions, this book takes a real-world approach, covering topics from basic and advanced search tools to online subject databases. Each chapter includes a thorough discussion, a recap, concrete examples, exercises, and points to consider, making it an ideal text for courses in database searching as well as a trustworthy professional resource.
