SCHOOLS and public libraries across Australia come together for one week each year to celebrate books and Australian authors and illustrators as part of Children's Book Week. This year the Children's Book Council of Australia is celebrating 70 years of Book Week. The theme for Children's Book Week 2015, which runs from tomorrow until Friday,   August 28, is Books Light Up Our World. And in the lead-up to Book Week the Children's Book Council of Australia has announced the shortlist and notable books for the Children's Book of the Year Awards 2015. The winners of the awards will be announced today in time for Book Week.
