game froze for me at the exact same location, when you walk down a set of stairs and books fall off the shelves. I think there are too many books and you have to wait until they all lie on the ground (too many objects to handle for the PS3?).
Another thing: is it normal that you lose the chapter select once you complete the game? I wanted to go back for some bronze trophies but I only have 'New Career' in the menu....
