01 March 2012 marks the 15th Annual World Book Day, an international celebration of children's literature which "aims to encourage a lifelong love of literature in children".
This year over 100 countries will be taking part in events to mark the day. The main international event will be 'The Biggest Book Show on Earth', an interactive online literary festival open to children from around the world. The online forum will allow young readers to watch online readings and take part in live question and answer sessions with some of the biggest names in children's fiction, including Jacqueline Wilson, Eoin Colfer, Derek Landy, Andy Stanton and Jeremy Strong.
You can also join the twitter discussions on your favourite childhood reads (#growingupiread) and discuss which fictional character you would most like to be for a day (#fictionalforaday).
Finally, Book Aid International have also launched their annual World Book Day appeal. Book Aid aims to increases access to books and supports literacy, education and development in sub-Saharan Africa. Last year they provided 516,138 new books to over 2,000 libraries and have sent more than 30 million books to partner libraries since 1954.
