Referring to my remarks on the use of the word "anonym," I may point out that this is not the correct title of Barbier's work.
You cannot express a negation such as this by a distinctive term like "anonym."
Ein Beitrag zur Zeitgeschichte und zum neueren deutschen Staatsrechte, anonym.
An′onym, a person whose name is not given: a pseudonym; anonym′ity, the quality or state of being anonymous.
The anonym had, like Scott, shirked, and had maintained his anonymity.
