Shelf Life points out what looks like a very interesting conference in London this December, "Books On The Move: Tracking Copies through Collections and the Book Trade" sponsored by the Antiquarian Book Association." Workshops will include "Lost': The Destruction, Dispersal and Rediscovery of Manuscripts," "What Can We Learn by Tracking Multiple Copies of Individual Editions?", and "Bibliophily and Public-Private Partnership: the Library of Gustave van Havre (1817-92) and its afterlife in Antwerp libraries".
More information here. Unfortunately this meeting comes just at the end of my fall term, but I'm going to look into making the trip nonetheless.
