I love used book stores! And I love that Kent has one! This place is much bigger than you'd think, and they have a pretty big selection, too. Have nothing to do one afternoon? Go browse the shelves here for a couple of hours. Chances are, you'll find some good gems. As with any used bookstore, you do need time and patience to navigate the shelves, but it's well worth it.
They also have a selection of movies and music, if you're so inclined.
The staff are very friendly, helpful, and knowledgeable, so they can probably tell you if they have what you're looking for. But my advice? Don't go in looking for something specific. Just browse around until something catches your eye!
