Here are the rules:

1. Books can be released in the wild or can be sent on a bookring, bookray, or bookbox, as long as they are sent away on the place and date of one of Leonard Cohen's World Tour concerts.
2. You can do it yourself or you can send your book to another bookcrosser in that location who will release the book for you.
3. All books released should have this words written somewhere: “This book has been released on the occasion of Leonard Cohen's World Tour, on the date and place of one of his concerts.” And the date and place should be written there as well.
4. No restriction in theme, although it would be nice if you explained in the JE of the book why you feel it should be released on that particular occasion.
