Warning: another post that is sadly not about Iceland.
But second best is good. Have you discovered BookCrossing? As so often happens, Wikipedia does a wonderful job of explaining it:
BookCrossing is defined as "the practice of leaving a book in a public place to be picked up and read by others, who then do likewise". The term is derived from bookcrossing.com, a free online book club which began and encouraged the practice. Bookcrossing.com's stated goal is to "make the whole world a library".
There are also shorthand terms for BookCrossing which are: BC, BCing, or BXing.
What could be better? Currently there are about 600,000 members, and I'm the newest for the next minute or two. Over 4 million books have been registered, and many are currently "in the wild". Soon I will select a favorite book to send off into the world, on its own journey. I'll keep you posted!
