This will be occupying much of my time between the summer of 2013 and the summer of 2014. I have a website (http://fantasticlondon.co.uk), and initially I am putting up my information on this website. But I am also exploring the possibilities of making it an app, for iPhone, iPad and maybe other devices. What I want to do is to list and map (a) the places in London associated with authors of science fiction and fantasy and (b) the places in London which serve as venues for science fiction and fantasy. I have already assembled a good deal of information, initially only on written sf and fantasy, but hope to extend this eventually to Fantastic London on the TV and in the movies. Here is a working list of the books set in London that I am looking at.
The website went live on 15 July 2013; there was a fallow period in the autumn, when I was busy doing other things, but I am back to inputting information, designing flags, etc etc. It should be improving pretty well every day!
