Having criticized Sean Wilentz about six months ago for not having gotten around even to scheduling the release of a biography of President Millard Fillmore in the American Presidents Series, I'll give the devil his due: the volume has now at last been scheduled. The release date is May 10, 2011.
The choice of author is interesting: legal historian Paul Finkelman of Albany, most of whose writings focus on race and slavery-related topics. Will Prof. Finkelman simply rake Millard over the coals for his endorsement and signature of the Fugitive Slave Act of 1850, or adopt a more nuanced view? We'll find out in due course.
UPDATE: In the comments, Prof. Finkelman explains that Prof. Wilentz was not responsible for the delay in the release of the Fillmore volume.
