Note 7 — OF DIFFERENT DESCRIPTIONS OF BOOKS.

A list, unfortunately containing many errors, will be found at the end of “A notice of the life and works of J. M. Quérard by Olphar Hamst: London, J. R. Smith, 1867.” This list is adopted by John Power in his “Handy-book about books,” with all my errors and a good stock of his own to boot. There is an extended treatise on pseudonyms in the introduction to either edition of Quérard’s “Supercheries Littéraires Devoilées.” The subject is also treated of in M. Octave Delepierre’s “Supercheries littéraires, pastiches,” Londres, Trübner, 1872. Probably the earliest treatise is that entitled “Auteurs déguisez,” Paris, 1690, by Adrien Baillet, but published without his name.
