The addition of new information
The construction of the site is an ongoing long-term project. New material is being published all the time, usually between the months of March and December, and 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.
Acknowledgements of help received occur throughout the site and are indicated by the use of the applause icon.
