A personal friend and overall great thinker once recited that books tended to reveal themselves to people at the right time and place. Some might say coincidence, I say fortune. Book Crossing attempt to engineer that experience by seeding the luck market.
The idea is simple. Register your book online and recieve a free BC-ID (Book Crossing IDentification) and release your book into the wild. This could be your favorite coffee shop, under a tree or any place of significance. Random people discover your book, read about book crossings, re-register the book online and begin reading. Users can track the books they release and monitor the progress. Alternatively, you can “hunt” for books in your local area.
Since consumers are the best critics, book crossings are an excelent way to discover books that impacted other peoples lives. I quote from the Ray Anderson the founder of Interface who attributes his companies environmental paradigm to a chance reading of the Ecology of Commerce by Paul Hawken.
