Spotting a little wheeled bookshelf packed with used books on Mill Avenue can be a welcome change to the rowdy clubs and weirdly lit women's clothing shops. It means you've reached the entrance to Old Town Books — a classic Tempe bookstore around since the 1980s. It's a cash-only operation run by an incredibly friendly older couple, and is jammed with used books and periodicals from floor to ceiling. The shop is general-interest in nature, but has expansive sections in Arizona, Native American, and Old West history. Old Town also carries vintage, first edition, and out-of-print books, along with the more familiar used books you'd expect to see.
