It’s from the Philobiblos blog and it discusses a couple of “companion” titles that we think you may find intriguing:
- Arthur Freeman, Bibliotheca Fictiva: A Collection of Books & Manuscripts Relating to Literary Forgery, 400 BC–AD 2000. London: Bernard Quaritch Ltd, 2014.
- Earle Havens, ed. Fakes, Lies, and Forgeries: Rare Books and Manuscripts from the Arthur and Janet Freeman Bibliotheca Fictiva Collection. Baltimore: Sheridan Libraries, Johns Hopkins University, 2014.
(Although, one of them may be outside your price range.)
