iSearch topic: Using Google to search Pay-for information

Using Google to search Pay-for information as reference for extended search -- add to iSearch materials.
Use Gartner browse, and other pay-for services' taxonomies to find keywords for WWW searches. It works pretty good for the sites that are open to searching; books24x7, IEEE, etc are not. It let's you use good terms from one provider and compare against another; and allows you to use the power tools from Google.
Not sure I would give up searching the sites independently, but when I'm faced with a needle in a haystack, and not sure where to start with my vendors, this is a good start.
