I met a friend that works in a public library over the weekend. They mentioned to me that they have joined to service called https://www.bookcrossing.com/. This service works on the basis that you register the book and then you can receive reviews and location reminders for book as it was swapped around. I have emailed book crossing to seek more information on the service. I was thinking the service may work well in our book swap section. Also it could good project for transition year student to complete.
