This website,, is devoted to the idea of spreading literacy by spreading literature--turning books into their own "messages in bottles". It works much like the "Where's George" currency-tracking website.

After being read by its owner, a book is registered on-line, and given a unique serial number (which is then written or pasted on a bookplate, along with the URL, inside the front cover). The book is then given to a friend, or placed in a conspicuous location in a public place, such as a booth in a restaurant, a seat on a plane, or wherever strikes the placer's fancy. The idea is that the next user to find the book can visit the website and see who has had the book and what they thought of it, and leave his own comments about how he happened to find the book and how he liked it.

Though the website has been in existence for about a year at the time of this noding, it has only recently begun to gain publicity due to appearances in Wired News and book periodicals. At present, very few books have more than one or two journal entries, and most of these seem to be due to friends passing the books on to other friends, rather than leaving them in the open for serendipitous discovery. However, there have been at least a few success stories. The people who have been so bookcrossed tend to describe it as a very uplifting experience--"like winning the lottery," as one put it.

It is too early to know how this additional publicity will affect BookCrossing; whether it will become another Internet fad remains to be seen. It seems, to this noder, a bit more useful than Where's George; currency is interesting to trace, but in the end, what good is it? Tracking a book provides a sense of satisfaction, and the idea that you have worked a positive change in someone else's life. It provides a sort of virtual meeting of the minds, connecting you together for a moment with someone from far away, whom you might never have known if it were not for that one book that brought you together.

My own BookCrossing page can be accessed via

Five years on from Robotech_Master's original writeup, and is going strong. Although the site appears to be of primary interest to book geeks and those with an obsession for tracing individual items, BookCrossing provides a worldwide free resource - free in both senses, as in beer and as in speech. This appeals to impecunious students, as well as to philanthropists with large book collections they want to get rid of. The concept is:

The World is a Library

The idea is that of serendipitous discovery. Books are left in public places: on park benches, in railway carriages, on cafe tables, ready for the next interested person to pick up the book and read it. The book contains a sticker inside the front cover, which contains a unique reference number, the BCID. Visiting the website gives the option for any anonymous person to key in the BCID, see the book crossing history of where the book has been, and add a journal entry to say where the book is now.

When you've finished reading the book, it's your turn to release it into the wild. Either put it back where you found it for someone else, or indeed leave it at a new location. Besides park benches and telephone kiosks, there are preferred locations "Official Book Crossing Zones (OBCZ)", where the proprietor or publican has given his blessing, and has something of a permanent display or shelf with BookCrossing books on it.

All of the above activities can be done anonymously. There are however benefits of joining the site as a named user. Doing so will give you membership of a worldwide growing list of bibliophiles, with on-line forums, conventions, meetups, competitions, book clubs and other community involvement. The commercial side of the site sells pads of stickers, post-it notes, waterproof bags, and anything else that is needed to release books into the wild.

Read, Register, Release

It's a good idea to use books that you have read or intend to read, as there is a fourth R, which is "Review".

When you want to register a virgin book, the website generates a unique BCID for you, and you attach a sticker and complete the BCID number. Many people register their own entire book collections, in some cases for posterity - the books will all get released into the wild when they die. I can see reasons for not putting a sticker in every book, as there may be many copies people want to give to friends as permanent possessions, or indeed sell on eBay.

When registering the copy of the book, there is an opportunity to give the book a rating and submit a review. The idea is that all books released into the wild will have mini reviews available on the website.

When releasing the copy into the wild, there is the opportunity to record a location of exactly where the book has been left. This updates the status of the book to "travelling", which it will remain at, until "caught" by someone finding the book and entering the BCID.

A comparison with book swapping sites

Most book trading sites work by way of exchange. Once people want to swap a pair of books, this is transacted using the postal service.

BookMooch is slightly different as there is a virtual currency of points, hence the give and receive transactions don't take place at the same time. I'm a heavy user of BookMooch, and currently carry an inventory of >300 books available for mooching. My objective is to reduce the number of books in my possession, and so far I have given away over 200 books.

The difference with Bookcrossing is that I can pace the rate at which I deplete my inventory, by choosing when and how many books I want to release in the wild. I've started an OBCZ today, and I am looking to initiate two more OBCZs in other parts of London.
