Andrew Muir published "Razor's Edge: Bob Dylan and the Never Ending Tour" in September 2001. The book chronicles the first fifteen years of Dylan's Never Ending Tour from the point of view of a committed fan of the Tour, analysing how Dylan varies his interpretations of his songs, and exploring Dylan's possible motivations. In July 2013, Muir updated "Razor's Edge" when he published "One More Night: Bob Dylan's Never Ending Tour": this book covers Dylan's touring activities from 1988 to 2011.
