Corrections

We check numbers and citations against their sources before we publish, but mistakes happen. If you spot an error on this site — a wrong figure, a broken link, a misstated fact, or anything else — email stetleaf@gmail.com with:

• the page URL;
• what looks wrong; and
• the source you think is correct, if you have it.

We'll review the report and, when warranted, update the page. When we make a material correction, we note the change and the date on the page.

There is no promised reply time beyond our good-faith effort to respond from the same mailbox.
