I read on several .edu websites that, although public domain information can not be copyrighted, still unique compilations of such information are copyrightable.
This has happened to me before, but it's the first time when someone copies my work and, a few months later they are right below my pages in Google's search results. I attribute this to their being a well known, fairly large company. The pages they put up are full of almost unintelligible sentences grouped around my content. What do you do in a situation like this? Is it worth sending a DMCA to Google?
