As you may have noticed, this site is not a vast resource of information. Its aim is to give the visitor a general overview of various topics, and provide links to other sites where more information is available.

All illustrations and diagrams were produced by myself, unless otherwise specified. If you wish to use any of them on your own web site, please let me know by e-mail.

Although I have tried to be as accurate as possible in my descriptions and in the data I have put on the site, there may be some mistakes or areas which I have not referenced properly. If there are, I apologise. Please let me know so that I can correct any errors.

In the mean time, I hope you enjoy the site. Feel free to e-mail me any suggestions for areas of improvement.
