Die einschlägige Sekundärliteratur wird bis zum Jahr 2005 erfasst, allerdings mit ein paar schmerzlichen Lücken: Dexter Edges Dissertation zu Mozarts Kopisten von 2001 ist von Sadie ebenso wenig rezipiert worden wie etwa Michael Lorenz' Untersuchung zu dem sogenannten Jeunehomme-Konzert oder auch die neuen Erkenntnisse zur Licenza KV 36 (33i).
The relevant secondary literature is being covered until the year 2005, but with a few painful gaps: Dexter Edge's 2001 dissertation on Mozart's copyists has been noted by Sadie just as little as Michael Lorenz's research on the so-called Jeunehomme concerto, or the new findings on the Licenza K. 36 (33i).
It is surprising that Brandenburg's gaffe was overlooked by the editors of the Mozart-Jahrbuch. Not only did Sadie take my research on the identity of the dedicatee of Mozart's piano concerto K. 271 into account, he also was one of the very few colleagues, who actually understood how the misnomer Jeunehomme Concerto came to be: the name Jeunehomme is a total fabrication, a figment of the imagination of Wyzewa and Saint-Foix. This basic fact seemed easy to understand after I had explained it in several publications. And yet according to a review by Ulrich Leisinger in the Mozart-Jahrbuch 2007/2008 (p. 139) the name Jeunehomme Concerto "is based on a misunderstanding". In the book Mensch Mozart!, published in 2005 by the Internationale Stiftung Mozarteum (and reperpetrated 2011 in English under the title Next to Mozart) we surprisingly are being told that the name Jeunehomme was caused by a "Verballhornung", i.e. a corruption:
It is to be noted by the way, that not at any price the solver of the Jeunehomme puzzle is to be named.
