From the outside, Books or Books looks pretty small, but when you walk inside and see shelves reaching to the ceiling, you know they are probably going to have more than one book on your to-read list.
The books are in pretty good condition and cost around $5-$7 (at least the fiction ones I picked out did). They seemed to have a big selection of romance, sci-fi, and YA books. They also have a Western section, local section, and true crime, which a lot of smaller bookstores lack. Fiction was disproportionately small for what I would have expected, but they had some really great titles in there.
They take cards, which is great, and the sales lady (who had an adorable PUPPY behind the counter, an extra bonus!) said they accept books for in-store credit, which is even better. This is exactly the kind of book store I was hoping I would find in Las Vegas, and I look forward to visiting Books or Books many more times.
