We read everything that arrives. Please put the reason in the subject line — it
is the difference between a same-week answer and a slow one.

## Editorial

Corrections, factual errors, an article you would like updated or removed:
**[email protected]**

If you are asking for a correction, a link to the article and a sentence about
what is wrong is enough. We do not need a formal letter.

## Rights and takedowns

If you own material that appears here and want it removed:
**[email protected]**

Tell us the URL on this site and the original you own. We act on these first and
we do not argue about them.

## Business and advertising

Sponsorships, partnerships, licensing the archive: **[email protected]**, or read
the [advertising page](/advertising/) first — it answers most of the opening
questions.

## Technical

Something broken, a feed that will not parse, a question about the Markdown
API: **[email protected]**

The site's machine-readable interface is documented on the
[agents page](/agents/), and the whole post index is one request away at
`/content/index.json`.

## Response times

One person reads each of these addresses. Expect a few working days. Rights
requests are handled ahead of everything else.
