I had always planned to publish my various works, if not free of charge then as cheaply as possible. So, for what they are worth, this site now contains a small number of the articles and talks that I have written or given over the past thirty years. It has to be said that much of this work, like my aching body, is both old and unreliable. Consequently, although the greatest care has been taken while compiling this site it almost certainly contains many errors. As such its contents should be treated with extreme caution. This is especially true of the earlier articles, which have simply been reproduced more or less as they first appeared. Neither I nor my fellow contributors can accept responsibility for any losses resulting from information or opinions, new or old, which are reproduced here. Some of the ideas and information have already been superseded by subsequent research and development. (I have attempted to included a bibliography for further information on such pieces) In spite of this I believe that these articles are still of considerable use. For PC logistical reasons it has not been possible to reproduce all of my illustrations. I have included the text for the series of posters that I created for the Strad magazine. While these posters are all still available, with one or two exceptions, they have all been reproduced without the original accompanying text.
