Average Reviews:
(More customer reviews)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 As others have noted, the static nature of print-on-paper means rapidly outdated material, but Sherman and Price show you how to attack the problem, so, even though I came across several (unfortunately) extinct databases, I was able to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.

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.
