"If you're making a claim about history . . . you should read, quote, and cite a work in that discipline. Do not rely on law review articles that make this assertion. . . . People who write law review articles are usually not experts in history . . . . Some are quite knowledgeable in th[at] field, but some have learned just enough to be dangerous. . . . And you particularly should not rely on secondary sources outside the underlying discipline, such as law review articles that cite history books; there the risk of error is too high."
-Eugene Volokh, Academic Legal Writing at 137 (3d ed. 2007).
