Bibliomancy is the art of using the words and sentences in a book to answer a question...picked randomly.
Although, I think it does work quite a bit better if it's a story that you have a general connection to and you consider most lines just full of wisdom. So, my Bibliomancy library looks (or will look, once I get copies of my own for all titles) like this:
The Neverending Story, by Michael Ende
Peter Pan, by J.M. Barrie (novel, not stageplay)
Alice In Wonderland, by Lewis Carroll
Alice's Adventures Through The Looking-Glass, by Lewis Carroll
Hans Christian Anderson's fairy tales
The Girl Who Circumnavigated Fairyland In A Ship Of Her Own Making, by Catherynne Valente
It's for the same reason my tarot card collection is 75% fairy-themed and like one zombie deck. Because I love stories about otherworldly journeys, and just feel more of a connection to them.
What's your bibliomancy library like? Or what would it be like?
