A figure that is wrong, a source that moved, a unit we should track: tell us and we fix the page, not just the reply.
Email hello@homerobotdata.com. Include the page and the maker page you are reading from; a correction with a source ships the same week.
Makers: we read your published pages. If a limit on our page is out of date, point us at the current page and we update it and its citation.
