For reasons clear to anyone who studies his Twitter feed and interactions, veteran Doctor Who fan Ian Levine is keen to make it known that
this short series of articles published in DWB in 1992 is available to read online. It's been supplemented and superseded by other work, such as Richard Molesworth's DWM articles and the two editions of his book
Wiped published by Telos, and by the ongoing work by the
BroaDWcast site, but it's still readable and tells Levine's side of the story as well as convey how horrified first-generation Doctor Who fandom was when they learned that episodes which they often remembered from childhood and which they imagined survived at some BBC vault no longer existed, with anecdotes of early fandom and the dawn of home video.
