Awards In May 2005 BookCrossing.com won two People's Voice awards in the Webby Awards for best community website and best social/networking website. BookCrossing was also featured in a BBC Radio project broadcast as 84 Book Crossing Road, which involved releasing 84 copies of Helene Hanff's book 84 Charing Cross Road around the world. The programme was nominated for a Sony Radio Academy Award in 2006. About Anyone who wishes to officially participate in "releasing" books, whether leaving it in a public place or passing it on to a friend, may register on the BookCrossing.com website, although there is the option to remain anonymous when "catching" or recording the find of a book. BookCrossing.com users can 'go hunting', where a member will go to the website to view a list of books that have recently been "released", then go to the location it was left to "catch" it.
