I just finished commenting on a blog post by Derek Wenmoth about searching the invisible web.

There’s probably a lot of duplication in the first two sites.
Unfortunately, the companion site for Chris Sherman and Gary Price’s book The Invisible Web is currently being “refurbished.” Their book is great though rather outdated. (It was originally published in 2001.)
I’ve bookmarked all these sites in my del.icio.us account with the tag “invisibleweb.”
