There was a time when Milwaukee was awash in great bookshops. This is not that time. But don’t fret because there is still a range of great booksellers purveying everything from fine literature to kids classics to cutting edge poetry to political works and more.

Though there are a number of chain shops, I have not included those, nor have I dwelled too heavily on used books, though I have included a few. After you visit these, you might want to delve deeper into some of the other shops – offering mostly pre-owned books.
