Divisions and Precisions

Book meme

Choose three books from your personal library that as a set of three would allow most of your friends to guess with reasonable certainty that they came from your house, and explain why if necessary. The aim is to pick books if possible such that any two of the three don't necessarily uniquely define you.

Any of Stephen King's Dark Tower books
The Complete Works of William Shakespeare
The Complete Idiot's Guide to Philosophy

Then choose three more that people would be surprised to find on your shelves (Terminal damage to your street cred is optional).

Any of the Harlequin romances hidden away on the bottom of my bookshelves.
Some really bad fannish biography of Brad Pitt I once got as a gag gift, unless I've already thrown it away.
Erm... a copy of the Book of Mormon, with passages underlined and everything!
