Yes, it appears that the one we're discussing is still copyrighted in Europe but not in the States. I can only see a version that shows the searched words and the page on which they're found in the book. The rest of the content is blank. If I read Robin's link well, that's what they do with books that still hold a copyright.
But I don't think Google, nor the the publisher of that book, will actively search for copyright infringement on a small forum. I am all for making proper reference to the author and publisher, and we would of course remove any copyrighted material at the first request of the owner.
Kind regards,
Bart.
