BookCrossing is leaving a book in a public place so it can be picked up and read by someone else, they in turn do the same. Every book has a unique BookCrossing ID number and the complete history of any given book’s travels is recorded by readers and may be viewed on bookcrossing.com.
Now an enterprising Finnish BookCrossing participant Miia Ranta has started applying BookCrossing ID numbers in datamatrix code to her BookCrossing books.
When this was suggested recently on the BookCrossing forums a couple of months ago, all kinds of objections were raised. Fortunately the objections can be easily overcome and enthusiasts may soon be able to scan the BookCrossing ID with their mobile and view the books history right there at the cafe table.
