Not long to go now: Novacon 40 takes place over the weekend 12-14 November 2010, at the Park Inn, Nottingham. The Guest of Honour is Iain M Banks, with Brian Aldiss as Special Guest.
Their website says that Novacon is the UK’s longest-established regional science fiction convention, held every autumn since 1971. It’s built around a single-stream programme mixing both literary items and more informal events, with deliberate emphasis on social contact between sf fans and genre professionals.
There is lots more information on their website.
