I just returned to New York from a 6 month solo backpacking trip through Asia. One of the things I really enjoyed about solo travelling was the book swap. Everywhere you went travellers would exchange books they had finished. I ended up reading amazing books I would never have picked up myself. Bookcrossing reminds me of the great book finds I had on the road. I think this is a great concept. I just hope I can separate from my favorite books that fill my shelves!!! (What do other bookcrossers keep on their shelves?
