The Doctor has made a mark on almost every era of history, and he's touched millions of lives across space and time. In these pages are some of the stories behind those brief encounters, each of them attempting to answer the question that must never be asked: "Doctor Who?" Designed as a scrapbook, each Doctor will have his own chapter, taking the reader through the era of the show and making references to specific episodes throughout. Contributors include Steven Moffat, Russell T. Davies, Paul McGann, David Tennant, Matt Smith, Neil Gaiman, and many more.
