Seen yesterday at an Italian conference: * http://www.cambridge.org/features/cambridgeLibraryCollection/faq.htm * https://www.youtube.com/watch?v=J-oA4sZ9nNQ (4 min, quite good)
They selected about 10k public domain classics and published anastatic reprints. What's interesting, they also do digital restorations of the scans to make the text more readable than the original.
I'm not sure if Cambridge claims copyright or whether such reprints are worth scanning, but the list of titles would probably prove useful for the English and Latin Wikisources. The project appears to be frozen since 2015, so a scrape of http://www.cambridge.org/features/cambridgeLibraryCollection/books.htm (or Amazon, if that's easier) would be a one-time effort.
