I would like to go on record that I am delighted at the very possibility of a book title such as The Structure of Spherical Buildings. Yes, I know they aren't real buildings (they do have apartments in them, however), but isn't the mental image one worth treasuring? Kudos to whoever came up with that title. I hope they did it on purpose.
This is a serious book on a serious subject. It definitely deserves the attention of anyone who is interested in the theory of buildings.
