For several years, I have been collecting copies of used books that contain Jorge Luis Borge's short story "The Library of Babel," a story about a library of infinite knowledge - a library so large and comprehensive that it contains a copy of every book ever written, every book that could be written - every possible combination of letters and numbers and languages. But what such a library could never include is the way in which a book changes by being read - the ways that the touch of the reader interacts with, and influences, the text itself. Using Kirlian photography - an electricity-based imaging technique - this project aims to reveal the hidden experiential history of the book. Any mark on the text that effects the conductivity of the electrical current should make a difference to the way the image appears - fingerprints, marks or underlines, coffee stains or other signs of wear and tear left by the owners and readers of the story.
