First off, I have become aware of the Medieval Science Fiction project, supported by the Centre for Late Antique and Medieval Studies at King;s College London. Their Twitter account is here, and they had a session at the International Medieval Congress in Leeds (the day after ‘Swords, Sorcery, Sandals and Space’ – had I but known!). There’s a write up here. They are doing much the same as we are for the Greco-Roman period, and I shall follow their work with interest.
The other link is the first part of Cara Sheldrake’s write up of the conference. I look forward to future installments.
Edit: And I want to add this CFP for a conference on Lois McMaster Bujold.
