  The Astronomical Genealogy Project (AstroGen) has been underway since January
2013. This project of the Historical Astronomy Division (HAD) of the American
Astronomical Society (AAS) has been online since July 2020, courtesy of the
AAS. The volunteers of the AstroGen team have systematically searched online
directories, mostly at individual university libraries, for astronomy-related
doctoral theses equivalent to the modern, research-based Ph.D. We now claim to
be 'nearly complete' for 38 countries, although some have not been updated for
a year or two or three. The website contains a page for each astronomer and
advisor, with links to the persons, universities, institutes, and the theses
themselves. More than two-thirds of the theses are online in full, although
some require access to a library with a subscription. There is information
about nearly 37,000 individuals who have earned astronomy-related doctorates
and another 5400 who have supervised them, but may not have earned such degrees
themselves. Most of the latter have not yet been evaluated, but probably a
majority earned doctorates in other fields, such as physics or geology. We
present some of the results of our research and discuss ten ways the reader
might make use of the project.
