Enormous expanses of the Internet are unreachable with standard web search engines. This book provides the key to finding these hidden resources by identifying how to uncover and use invisible web resources. Mapping the invisible Web, when and how to use it, assessing the validity of the information, and the future of Web searching are topics covered in detail. Only 16 percent of Net-based information can be located using a general search engine. The other 84 percent is what is referred to as the invisible Web—made up of information stored in databases. Unlike pages on the visible Web, information in databases is generally inaccessible to the software spiders and crawlers that compile search engine indexes. As Web technology improves, more and more information is being stored in databases that feed into dynamically generated Web pages. The tips provided in this resource will ensure that those databases are exposed and Net-based research will be conducted in the most thorough and effective manner. Booknews Much of the Web remains opaque to search engines (hence the term "invisible Web"). Sherman and Price have written this detailed guide for computer literates who wish to improve their Web navigation and novices who wish to learn how the Internet works and become an accomplished searcher, as well as less ambitious readers who will love the long selection of sites with a complete description and the address spelled out.
