If you buy books, it is the book building near Wuhan University of Technology. There are not all books, but there are many books. Just take a bus directly from Wuchang to Book City, which seems to be at 703.

If you borrow books, Hubei Provincial Library is the largest. The school library doesn't have all the provincial maps, and there are very old versions.

Hubei Provincial Library is in the cavalry training ground, and there are cars everywhere in Hankou/Hanyang/Wuchang. 100 you can borrow books for one card, and the books are complete.
