Definitely not as nice or big as the libraries at Paseo Verde or Green Valley. However, the staff are helpful and courteous. There are some pretty good facilities, childrens section, a computer section, magazines, DVDs, and lots of books. The selection isn't as big as the one at Green Valley though. The building looks kind of dark and unwelcoming, to be honest. Some sketchy looking people sometimes, but then again it's at a sketchy part of town.
The best thing to do is to go in (or any other library), get a library card, then go to mypubliclibrary.com sign up and search, order and hold books from there. They will transfer the books from the other libraries to you so you just have to pick it up from there. It takes about a week for the books to be transferred, and they also hold the books for another week. You can also renew books online.
