Isn't multiple floors of bookshelves with open central area a very common theme in large fancy libraries? For example British museum reading room, Oval room in France national library, Morgan Library & Museum, Rose reading room in New York Public Library.
The shelves can't be very high to keep them easily accessible, adding additional levels solves that. Open central area with higher ceiling gives more natural lighting.
