About Time volume 4 covers Seasons 12 to 17 of Doctor Who, focusing on the Tom Baker era in mind-bending detail. In addition to the usual concerns such as the TV show's continuity (alien races, the Doctor's abilities, etc) and lore (anecdotal, "Did You Know?"-style material), authors Lawrence Miles and Tat Wood will examine each Tom Baker story in the context of the year/historical period it was produced, determining just how topical the stories were.
Essays in this volume include: "Does This Universe Have an Ethical Standard?", "Why Couldn't They Just Have Spent More Money?", "Which is Best, Film or Video?", "How Badly Does Dalek History Suffer?", "September or January?", "What Does Anti-Matter Do?", "Where (and When) is Gallifrey?", "Why Does Earth Keep Getting Invaded?", "Who Are All These Strange Men in Wigs?", "Is He Really a Doctor?", "Does the Universe Really Speak English?", "Did Rassilon Know Omega?", "Is This Really an SF Series?", "Cultural Primer #1: Why Top of the Pops?", "Bad Effects: What are the Highlights?", "When was Doctor Who Scary?", "Cultural Primer #2: Why Blue Peter?", "Is This the Quatermass Continuum?", "Just How Involved are the Time Lords?", "How Might the Sonic Screwdriver Work?", "What Do the Guardians Do?", "Cliffhangers: What are the High and Low Points?", "The Obvious Question: How Old is He?", "How Hard is it to be the Wrong Size?", "War of the Daleks: Should Anyone Believe a Word of It?", "When Did the Doctor Meet Leonardo?", "How Do You Transmit Matter?" and "What Else Didn't Get Made?".
