Beach goers select books from 30 red Ikea Billy bookcases lined up to form the world's longest outdoor bookcase to celebrate the 30th birthday of the brand's signature furniture piece, at Bondi Beach on January 31, 2010 in Sydney, Australia. The bookcases were filled with thousands of books which beachgoers can swap for one of their own or make a gold coin donation to buy, with proceeds to The Australian Literacy & Numeracy Foundatio.
