Editorial policy
Here are the rules we follow when preparing texts: who is responsible for them, what they rest on and how quickly inaccuracies are fixed.
Authorship and responsibility
The same person writes and proofreads the texts, so there is always someone answerable for each statement on the site.
Material on this site is prepared and checked by Marcus Ellery.
How facts are checked
Figures, dates and quotations are checked against the primary source. When a statement relies on someone else data, the text names the owner of that data and the period it covers.
How to report an error
Write to us through the contact form and give the address of the page. A confirmed error is fixed, and the piece gets an updated date together with a note on what exactly changed.
