Corrections and correspondence

Corrections are welcome, and the more specific the better. If a date, a figure, a title or an attribution on this site is wrong, write with the piece it appears in and the source that corrects it, and it will be changed.

Write to [email protected]. Requests to add a claim without a published source will not be answered; requests to correct one will.

Image and photography credits sit under each figure. Rights enquiries go to the same address.
