Product Description
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.

 Invisible Web book January 26, 2008

This is an excellent book if you are heavily into the search process. It begins with a basic understanding of the internet, the web and how search engines work. It then proceeds to explain what the 'invisible' or 'deep' web is, how to recognize it and how to deal with the search process of it. It includes a huge section of reference sources on the web.
Technical explanations for the truly web-savvy February 27, 2006

The author is the unsurpassed guru of InterNet searching, and is explicitly relied upon by other authors engaging in the same work. His website is the mother lode of additional information, which is very helpful. If you have one book on your shelf regarding InterNet resources, this should be it. That said, Mr. Sherman relies heavily upon explanations of the breadth and depth of various resources; these explanations are designed to pique the reader's interest in further self-directed exploration, but may be more than the average searcher might need.

 Excellent instruction for librarians . . . June 12, 2003

I retired five years ago after thirty years in a very large public library system, and recently found it necessary to return to the trenches for awhile, in a rather smaller system. In that half-decade, of course, the Internet changed drastically and, even though I'm constantly online and intimately familiar with the major search engines (and many of the minor ones), there was a large number of new reference information sources with which I was not at all familiar. So I went looking for professional tools to remedy my ignorance. This is the first book I've seen in the publisher's "CyberAge" series, and medthodologically, it's quite good. As others have noted, the static nature of print-on-paper means rapidly outdated material, but Sherman and Price show you how to attack the problem, so, even though I came across several (unfortunately) extinct databases, I was able to locate several new ones, too. This is a terrific instructional work for reference librarians, and the accompanying web site is near the top of my bookmarks at work.
Great guide to out of reach resources May 29, 2003
9 out of 10 found this review helpful
"The Invisible Web" is a thorough, thoughtful guide to finding information lying just outside the reach of search engines. It can be divided into two parts.The first part describes the strengths and weaknesses of search engines as tools for finding information on the World Wide Web and provides a good overview of the technical and business limitations that lead to the weaknesses. At the same time, the authors also provide a high-level explanation of how search engines operate and a comprehensive explanation of what types of resources are left out of search engine indexes. Although this section is a bit repetitive, it also stands as the best explanation I have encountered on the subject of Web resource accessibility (and inaccessibility) through the popular tools that searchers have at their disposal. The second part provides a list of Invisible Web resources (resources that can not be indexed by search engines), organized by subject, with annotations. I personally did not find this list comprehensive, but it is a good place to start for those who have previously relied solely on search engines and directories for Web searching. If you want to understand what resources are just beyond the grasp of search engines, and get a hand on them yourself, "The Invisible Web" is a great book to get you started. Note: some of the URL's sited in the second part of the book are now gone. This is not a criticism of the book, but a reflection of the ever-changing nature of the Web.
