I love working at the Georgia Tech library. Open 24/7 during the business week and it's nice and quite. It's one of the greatest perks of going to Georgia Tech for me.
Edit: Well, I totally misinterpreted what the author meant by "work at". This'll teach me to RTFA I guess.
FWIW, GT's library does rock. They have quiet area as well as group areas and a great set of workstations as well. The only thing missing is a decent coffee machine.
