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?
Compared to you guys I feel boring and old :P I use The Oxford Library of English Poetry vol. II. The poetry has always appealed to me. I've never tried using fantasy but I imagine you can get some pretty unique results.
I'm lucky to have started collecting books when I was a kid so my collection is big (but not big enough), so I usually pick one of my books at random. Close my eyes and pluck type deal. Usually when I have a question I turn to the scrying waters or to bibliomancy (if I don't turn to the spirits for aid). My collection is assorted by alphabetical genre, so when it comes to bibliomancy I tend to go to the section most relevant to my question.
Ive turned to the Dark History of Kings and Queens of England for multiplw questions, enough times I think it's my go to book for broad questions. I also turn to my bible and my copy of Romeo and Juliet. Besides those three books, it's pretty much a random pick.
