Partners World Book Day was designated by UNESCO as a worldwide celebration of books and reading, and is marked in over 100 countries around the globe. World Book Day is a partnership of publishers, booksellers and interested parties who work together to promote books and reading for the personal enrichment and enjoyment of all. A main aim of World Book Day in the UK and Ireland is to encourage children to explore the pleasures of books and reading by providing them with the opportunity to have a book of their own. For 27 years Hay Festival has celebrated great writing from poets and scientists, lyricists and comedians, novelists and environmentalists, and the power of great ideas to transform our way of thinking.
