I realize this is yet another public domain collection, and the contents are probably available for free at so many places, plus, I'd rather have them all individually, but Bookhouse, has a 2 book set currently for free at Amazon
Book 1 Book 2, and at Kobo
Book 1 Book 2. They've had several other free PD collections, but I've never checked on their quality. There are several other non-free collections with similar names, I assume with the same PD list. I know I've seen most of them as the daily free PD ebook from Open Road Media over the last year or two as well.
If you're curious about the list, here it is:
