The historian Deborah Lipstadt (Denying the Holocaust: The Growing Assault on Truth and Memory, 1993), and the historians Michael Shermer and Alex Grobman (Denying History: Who Says the Holocaust Never Happened and Why Do They Say It?, 2002), distinguish between historical revisionism and historical negationism, the latter of which is a form of denialism. Lipstadt said that Holocaust deniers, such as Harry Elmer Barnes, disingenuously self-identify as "historical revisionists" to obscure their denialism as academic revision of the historical record.
