Law students check it out!!
I'm a nerd. That being said, this place is really cool. It's across the street from what I would have to call my fave used book store, but they both have their strengths.
This one has old books, new books, and a legit selection of law treatises. Law students check it out!! It would be worth a gander to see if you can get something cheaper here than your university's own bookstore, even at their used price.
They also do a bunch of specialty sections. They are smaller than the one across the street but I would look in here if you are going to look in the other one anyway. They have a book club I believe, if you are into that sort of thing, although I have never really checked that out. I went there at first to look up some resources for a project on gender and law and found some helpful titles.
They also have some good art history books too. Definitely check it out if you are in the area!
