Shaun Usher lives for letters, lists, and beautiful books. In 2009, his love of correspondence resulted in the launch of Letters of Note, an online museum of notable letters which to date has been visited almost 100 million times. Four years later, that website spawned a much-anticipated book of the same name, the first of three books of note to be crowdfunded with Unbound; it was published in 2013 to widespread acclaim, has since become an international bestseller, and resulted in Letters Live, a star-studded live show in which these letters are brought to life on stage.
