Book Crossing is an initiative that began in 2001 where book lovers register and release books to be discovered by others. Over 9.5 million books have been released across 132 countries. Parramatta City Library participated by releasing 70 books and tracking their journeys online. The program aims to promote reading and make connections worldwide. While expectations of returns need managing, it is an enjoyable way to share books and the library hopes for future messages from books traveling in the wild.
