Here is a quick photo tour of the Friends of the Hoover Library Used-Book Store. It’s located on The Plaza back near the magazines and snack bar and there is another “secret” room downstairs that has $1 books!
They keep carts outside the shop with $1 books. Its always worth looking through as 90% are hardbacks and many are donated (a.k.a. books without library markings/stickers). They have a nice easy to understand pricing system once inside.
Now the Library Used-Book Store keeps an overflow room of used books downstairs along the wall of the community room. All of these books in the “Book Nook” are $1. The turnover here isn’t as high as upstairs so I don’t check on this every visit. But I have found some gems there. So do check often.
To get to the room, go back out to the main library hallway and follow it around towards the non-fiction sections. As you are approaching the “quiet study cubicles” there will be a stairway on the right. Take this downstairs. Once downstairs take a left and you’ll see the room.
