Those Dark Hiding Places: The Invisible Web Revealed

Interesting website "Those Dark Hiding Places" for providing ways of accessing the 'Hidden Web'.

"Although many popular search engines boast about their ability to index information on the Web, more of it (dynamically-generated pages, certain file formats, and information held within numerous databases) has become invisible to their searching spiders. Much of the Web is hiding information from us, but we can access this hidden content!...

"Because much of this information is not accessible to many general search engines' software spiders, we need to look for specific search tools that will lead us to this hidden content. Some of these tools include directories, searchable sites, free Web databases, and a few general and many specialized search engines."

Definitely worth a look at
