I believe that they've got a copy of Elhanan Winchester's "The Universal Restoration"
Not sure about the title but I'm certain I downloaded something of Elhanan Winchester.
Pitty it mostly (all) are non OCRed books. So I'll miss teh search function of a e-book.
I changed the title from 500+ to 200+
Partly because I got 5 pages of hits when I searched; but when I went to page 2 suddenly Google reported a total of 3 pages. Some book aren't even about religion.
Try other keyword combinations for other hits.
Search tip: Goto advanced and select complete view. Those are the only out of copyright that can be downloaded.
If Martin doesn't mind I would like to use this thread to exchange titles of good books found on Google books.
