Possibly out of date
I was pretty excited about the site, but there are no “last updated” notes on any of the pages. I tried to contact the authors using the email provided, but the email bounced. Also, I didn’t see any sources on at least one of the pages that was more current than 1999 or 2000. It could be that it’s still fairly sound information, but as an authoritative site, it’s a bit sloppy.
