I'm helping my folks clean out their shelves and I've run across plenty of books without ISBN's.   I'll be adding to this post as the days go on, but for now here's my list.  Same rules as PBS--- 1 book for 1 credit.

Allan Sherman - Rape of the A.P.E (Amerian Puritan Ethic): History of the Sexual Revolution 1945-1973.  Hardcover. Playboy Press, 1973.

It's really not as dirty as it sounds.  Allan Sherman's cult classic book on the sexual revolution.  Sherman tackles the history of sex in America in a sprawling, eccentric, hodge-podge of wit, history, wordplay, autobiography and anthropology. Hilarious and truthful at the same time.  The dust jacket shows some wear, but the book is in great shape.
