I have had an interest for a long time in Alphonse Labitte (see, for example, the blog post here). In 1890, he founded the Société des Miniaturistes et Enlumineurs de France, and I assume it was a sort of club, perhaps a bit like the Burlington Fine Arts Club, with a regular meeting-room and its own library (to which, I guess, members were encouraged to make donations): in his various publications he often reproduces manuscripts in the "Bibliothèque ed l'enlumineur". Or perhaps he referred to his own personal library as if it belonged to the club; I have found at least 22 medieval manuscripts that bear his bookplate. But until now, I have not been able to match up any of the manuscripts he reproduced with manuscripts whose present whereabouts I know.
The exception is a miniature now at Columbia University, shown above.
