PLEASE NOTE

All the video recordings on this website were made at least a decade ago.  Some are fifteen years old.

What the speakers say on camera was based on their own knowledge and researches at the time each video was made. Since then a great deal of information has come to hand which may make some of the information first recorded now outdated. Therefore please regard  this website as a period piece presenting knowledge held and believed at the time of recording.
