The construction of the site is an ongoing long-term project. New articles and images are being published all the time, articles are being expanded, captions lengthened, and errors corrected as they become known. This will continue for so long as the site generates its current level of visitors and feedback.

The list of Sources consulted and the Illustrations index and picture gallery are cumulated each month.

'Thank you' icon Acknowledgements of help received occur throughout the site and are indicated by the use of the applause icon.
