Shaun Lyon has written two short stories for Big Finish's Short Trips range, as well as Back To The Vortex: The Unofficial and Unauthorized Guide to Doctor Who 2005 and Second Flight: Back to the Vortex II - The Unofficial and Unauthorized Guide to Series Two, covering the first two seasons of the new Doctor Who TV series, for Telos Publishing.
From 1995 until the site's closure, Lyon was the editor of Outpost Gallifrey, the prominent Doctor Who website and managed the Doctor Who Forum. He is also the program director and co-founder of the Los Angeles-based Gallifrey One convention.
On 2 June 2009, Lyon announced that he was closing Outpost Gallifrey, its associated Doctor Who News page, and the Doctor Who Forums. In his announcement he does not cite a specific reason for shutting down these popular websites. He does indicate that his association with the Gallifrey One conventions will continue.
