From Alan Bennett's Baffled at a Bookcase, to Lucy Mangan's Ten Library Rules, famous writers tell us all about how libraries are used and why they're important. Tom Holland writes about libraries in the ancient world, while Seth Godin describes what a library will look like in 2020. Lionel Shriver thinks books are the best investment, Hardeep Singh Kohli makes a confession and Julie Myerson remembers how her career began beside the shelves. Using memoir, history, polemic and some short stories too, The Library Book celebrates 'that place where they lend you books for free' and the people who work there. All royalties go to The Reading Agency, to help their work supporting libraries.
