How to put off many books

I continue to clean up my room after I’ve moved to new house. I worry about how to put off many books that I brought from family home and I can’t store in new house such as technical books and novels. It is “MOTTAINAI” to put off as dust so at first I’m planing to sell in Amazon market place but I recognize it is troublesome and low margin task with respect to spend much time to register the book, respond to buyer, send book, inform them. So I’ll request to cutting vendors to cut books and after that I’ll scan them as PDF or JPG data to read by some devices and I can save the space in my house.
