Missing is The Real Animal House: The Awesomely Depraved Saga of the Fraternity That Inspired the Movie, by Chris Miller. I lent it to my brother, who is a big fan of the movie (I sort of bought it for him too). I haven't yet read any of them, but I will probably start one once I finish one of my current reads (I'm juggling three books at the moment).
I already had an older copy of Regency Buck by Georgette Heyer, but I love the cover art on these newer editions. Besides, the old one is liable to fall apart if I try to read it.
