3rd Doctor Expanded Universe Sourcebook 2018 Addendum (2018)

From the introduction:

Since we last published Unauthorized Adventures in Time and Space: 3rd Doctor Expanded Universe Sourcebook, we’ve discovered even more of his extracanonical adventures. The Third Doctor hasn’t been sitting still, and neither have we.

So we’re presenting the Addendum 2018, catching us up with UNIT’s scientific adviser, covering the Big Finish audios that have been released in the years since the core book hit the Internet, as well as a few short stories and comics besides. We’ve gone back to the old comic strips and brought more of that material into focus, including an off-model Doctor to play with. Plus, we’ve added some entries in the Omitted but not Forgotten section; between all the sourcebooks dedicated to the Third Doctor’s adventures, no TV story is left without at least one stat-blocked character.
