Also the trend for free book exchanges in disused phone boxes! My local village has a working phone box, presumably because mobile phone service is lacklustre! It has still become a community book exchange despite being live!. I'm reading one of their books right now actually! One of the classic orange Penguin editions of 'Carry On, Jeeves' by P.G. Wodehouse!
It also mentioned, at the end, the trend I'd noticed for schools, supermarkets and others to have places to trade second hand books for free.
