I have had a suggestion from Eileen Murphy to get a book list going - where we can list relevant books etc. I have made a start on this by adding an amazon 'widget' to the front page, including the various books I know of. I am happy to add other books to it of course - please suggest away.
The drawback of this system is that it will only show books available through amazon.co.uk, which probably excludes (for example) the German edition of Peter Roehrig's activities book. So there may be another way to do this. I am actively looking for a way to start a list which can be added to/edited by all - will keep you posted.
