There are other free e-book sites that will get around the Google error message -
www.manybooks.net and
www.epubbooks.com are two of my favorites, plus there's an "E-Book Upload" forum on MobileRead. I've also found that books from these two sites tend to be mostly free of the errors and weird formatting that I've seen in the Google books; I think it's because the Google books are scanned in and the others are copied in by hand. Most of the books on my 650 are from one of these sites...what can I say, I love classics and I love freebies.
Give them a try!
