Such books are to be cherished, and a person is rewarded for copying them, whether for personal use or for sale. As the Prophet, may Allah bless him and grant him peace, said:

“Allah admits three people to Paradise through a single arrow: its maker, the one who shoots it, and the one who supplies it.”

The same applies to copying books: whether one does so for one’s own benefit or to benefit others, one is rewarded in either case.
