There is 1 bookstore in #yxe west of idlewyld (which bisects the city east/west almost as well as the river does), and walmart. That's it. And that bookstore seems to be a hipster store, and it's probably hit or miss what books they have / don't have. They might be able to order direct from publishers (there's a bookstore on the east side that can) but still
it's a crapshoot getting books
