Here's a weird rabbit hole. This piece by #ColinWoodard very obviously expands on David Hackett Fischer's seminal 1989 book #Albion'sSeed. But Woodard doesn't mention Fischer anywhere in the article, instead citing a1992 article by #RichardNesbitt, which *also* doesn't cite Fischer.

Woodard's book on Amazon doesn't have a bibliography, but neither Fischer nor Albion's Seed are in the index.

That kind of omission would get you a failing grade on a seminar paper.
