Based on the books on your bookshelf, what conclusions would people draw about you?
That we have enormously wide and various tastes ranging from Old West history to English Royalty to Religion to mental health to science. "Steven Hawkings in my library," yes, indeed. Of course, all our fiction is currently packed away, so the shelves are ALL research/non-fiction/history/etc., except for some favorites, comic collections, and just about everything by Tolkien.
I'm not sure exactly what other people would think about our book collection, other than my mom, who wondered why we needed SO MANY (Mom is a "read 'em and get rid of 'em" sort -- it's not that she doesn't read, she doesn't KEEP).
