Great place to chat w/ friends over a coffee & perhaps a pastry, soup, or sandwich, but not so much for studying or reading.
I've made it a routine to go through the CDs here whenever I am at Crossroads-- I've found so many gems, rarities, & steals in the past!
Lots of study/reading nooks scattered around the library, and most of them have an outlet somewhere nearby, in case you need them-- great place to get stuff done.
