World Book Night is an annual celebration of reading and books that takes place on the 23rd April. It sees passionate volunteers give out hundreds of thousands of books in their communities with the aim of spreading their love of reading, to those that don't read regularly or own books. WBN is run by The Reading Agency, a national charity that inspires people to become confident and enthusiastic readers.
World Book Night took its lead from the well established and successful children's reading celebration in UK & Ireland called World Book Day. So as day is for children, then night is for adults.
2015 will be the fifth World Book Night celebration.
