How about Hell No?
The book would fetch more than the price you're offering if I sell it on Amazon, Ebay, or to my local game store. That's Strike One.
You want me to destroy it's inherent value by taking it apart, and then offering nothing to rebind it back to original condition? My Librarian Overlords would burn you at the stake for even THINKING such an atrocity. Strike Two.
You then want to profit handsomely off my labor by reselling the digital scans, while cutting me out of the fruits of my hard work? Strike Three, you're outta here.
I *might* be willing to take my stuff to my local Library & have them unbind, scan, & rebind the books, so THEY can offer digital copies for customers of the Library, because that would not only treat the books with the respect they deserve, it would ALSO result in the information being Made Available for the low low price of a Library Card.
As others have mentioned, you can probably find most if not all of what you're seeking via a simple torrent search, or you could search Amazon/Craig'sList/Ebay/etc for sellers of said material, or you could pay a fair rate for the professional scanning of private collections. But to offer a pittance so we can destroy our own property & be left with now worthless scrap?
You're not just out of your mind, you've gone off the deep end with an anchor shoved up your arse.
