2Sherman, C. ; Price, G.: ¬The invisible Web : uncovering sources search engines can't see.
In: Library trends. 52(2004) no.2, S.282-298.
Abstract: The paradox of the Invisible Web is that it's easy to understand why it exists, but it's very hard to actually define in concrete, specific terms. In a nutshell, the Invisible Web consists of content that's been excluded from general-purpose search engines and Web directories such as Lycos and LookSmart-and yes, even Google. There's nothing inherently "invisible" about this content. But since this content is not easily located with the information-seeking tools used by most Web users, it's effectively invisible because it's so difficult to find unless you know exactly where to look. In this paper, we define the Invisible Web and delve into the reasons search engines can't "see" its content. We also discuss the four different "types" of invisibility, ranging from the "opaque" Web which is relatively accessible to the searcher, to the truly invisible Web, which requires specialized finding aids to access effectively.

3Sherman, C. ; Price, G.: ¬The invisible Web : uncovering information sources search engines can't see.
Medford, NJ : CyberAge Books, 2001. 402 S.
Abstract: 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. Discusses the use of online information resources and problems caused by dynamically generated Web pages, paying special attention to information mapping, assessing the validity of information, and the future of Web searching.
