10 writers cannot keep 790 pages perfectly current on their own. If you find something wrong, telling us is genuinely useful.

One address for everything: [email protected].

  • To report an error, name the page and say what is off. Nothing gets our attention quicker.
  • To suggest a product, tell us which and why it belongs.
  • For anything commercial — rights, reuse, press — the same address works.

Every message is read. Not every message gets an answer — corrections do.

What to send somewhere else

Nothing is sold from this site, so we cannot see or change an order. Deliveries, refunds and returns belong to Amazon; faults, warranties and manuals belong to the maker. We hold no record of any purchase.
