A former bookseller and Web-site editor, Travis Elborough has been a freelance writer, author, and cultural commentator for the last decade. His books include The Bus We Loved: London's Affair with the Routemaster and The Vinyl Countdown. Nick Rennison has worked as a writer, editor, and bookseller for more than twenty years. His London Blue Plaque Guide has been through three editions in the last decade and he has also published The Book of London Lists, described by the London Evening Standard as a book that "can teach even the most die-hard Londoner something they didn't know." Both of them live in London.
