The Fourth Edition of AHistory amends and vastly expands (by about 40%) the work of Third Edition, continuing to incorporate the whole of Doctor Who into a single timeline. All told, AHistory Fourth Edition takes about 2000 (!!!!!) full-length Doctor Who stories and dates them in a single chronology -- starting with the Universe's origins and working its way forward to the end of time. Volume 3 (of 3) of this series includes the universe's Future section -- from 2018 to its final, sputtering heat death.
