Editorial policy
This page explains the rules by which material appears on the site. Corrections to published work are described in the same place.
Authorship and responsibility
Every publication goes out under the author's name. Any statement can be questioned directly — the contact details are open.
Material on this site is prepared and checked by Rachel Whitfield.
What backs up the statements
Any figure in the text can be traced back to the document it came from. Outdated information is replaced, not flagged in small print.
Feedback and corrections
An error report is reviewed within a few working days. The fix is made in the original text, not tucked away in a separate note.
