Corrections and sources

The useful message to send this site is a correction with a record attached.

Corrections

If an entry states a mechanism wrongly, or attributes a figure to a record that does not contain it, that is worth reporting. Name the entry, quote the sentence, and cite the record you are working from. Corrections are made in place.

Sources and permissions

Photograph credits appear beneath every figure, with the holding institution or photographer named. Requests about reuse should go to the named holder rather than to this site.

What cannot be answered

Questions about what to do with money are not answered here, in public or in private. This site describes mechanism and record, and it has nothing to say about anybody's circumstances.
