I'm one of those people that prefers to keep the original books and manuals in pristine condition if possible. I currently use copies of the original two books in folders to use while keeping the originals tucked away for safekeeping.
Are there PDFs of the two tombs available anywhere yet?
Where did you find copies for the base game? All I saw them release was fixed versions for the 1st edition because they had errors in them. I've never seen any for the 2nd edition. I too like digital copies of manuals and whatever other books come with games, and can't even find a copy of the rulebook for Widow's Walk. Does it even come with one? My copy won't be here for a couple weeks, so I can't even look.
I'd like to find them as well.
