A recent post at A Snail’s Eye View was about the conchology book Edgar Allan Poe wrote, or rather plagiarized.
Hoping to find a digitized copy of Poe’s book, I searched Google Books, but came out empty handed. There are, however, a whole bunch of 19th century conchology books Google has scanned and most of which are undoubtedly more original than the one Poe put together.
I am providing a partial list only. If you want more, try searching Google Books for "full view books" using any combination of keywords that you might think would be relevant to conchology or malacology. One cautionary statement about Google Books: you will notice that they don’t seem to have a very good quality control system; occasionally there are missing, misplaced or poorly scanned pages.

Incidentally, this appears to be the scan of the personal copy of the American malacologist (conchologist?) Henry Hemphill. His name was stamped on some pages.
