i.e. getting the SDK. Pleas, are these SDK's paper books or CD's or what? If they are books, please what is their publisher and full title and ISBN number, to make life easier for my bookseller?

There has been much discussion about this on the email group fab-ufo@lists.pipex.com (about the Gerry Anderson UFO series, archives on http://www.lists.pipex.com/cgi-bin/digests?list=fab-ufo ) when matters turned to people making .AVI's and .MPG's of scenes related to the series.
