The interior of this building is gorgeous and in the modern style, and I swear that upstairs where the media borrowing center is looks like a Barnes and Noble. In addition to a wide selection of books and sitting areas, Carnegie lends out DVDs and CDs. I was really pleased at the great balance between mainstream movies and Indie documentaries. Borrowed a stack of CDs too for burning at home.
A great place to spend the weekend, and I recommend bringing visitors to Pittsburgh here as well.
