Contact Us
One address, read by the person who makes the site.
There is no contact form, because the site has no backend and keeps no data about its visitors. Email goes straight to the mailbox above. Expect a reply within a few days; corrections are usually applied sooner than that.
What to write about
- A correction. A diagram, a sentence or a table cell that disagrees with a source you trust. Include the page, the claim and the source; the Methodology page explains how it will be checked and recorded.
- A question about a binding that the pages leave unanswered. The most useful ones become new FAQ entries.
- A permissions request to reuse a diagram or a passage. The terms page says what is allowed without asking.
- A privacy question about advertising, cookies or consent, covered on the privacy policy page.
What this address is not for
The site does not recommend printers, binderies or suppliers, does not sell anything, and does not accept sponsored content, link placements or guest posts. Messages asking for those go unanswered.
