9 writers cannot keep 1,806 pages perfectly current on their own. If you find something wrong, telling us is genuinely useful.

There is no form here, just an address: [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.

You will hear back about a correction. For other mail we do our best and make no promises.

Things to take elsewhere

Please do not send order numbers — we have no way to use them. Amazon handles delivery, returns and refunds. The manufacturer handles defects, warranty and documentation. We are neither.
