Librarian in Black Blog – Sarah Houghton

Luke Rosenberger shares a nice list of six stock photo sites.  As he points out, their databases of images aren’t crawled by image search engines, like Google’s, so you need to keep these sites in mind when you’re looking for good stock photos (for web, print, or e-mail purposes).  The immensity of resources in databases like this is a good example of the true value of the invisible web.
