The Bissell library or “the biz” is the most recognizable building at OU. I spend many hours a week in this building studying away.. Always on the 3rd floor. I really enjoy this building for the beauty of it, the space, and the study areas. The Great reading room is absolutely beautiful, but its a little intimidating at times. I enjoy the old and new parts of this building. I wonder how long the new renovated lower level will last?
