The bedroom bookcase holds all my fiction (top shelf only) and all the New Age or spiritual books, self-help books, and books on world religions. My fiction is only the one shelf any more since I joined www.bookcrossing.com. I usually release my fiction books now and pass them on.
I prefer to look up the word, but--again--it depends on what I am reading, where, and how tired I am--ROFL! I have read many a book in my day with the dictionary by my side. :)
