The Conspiracy of Pontiac

Starting with an enlarged edition in 1870 -- which incorporated newly available Bouquet and Haldimand papers from the British Museum -- Little, Brown reset and reissued the work as a two-volume "revised edition," and later folded it into multivolume "Works of Francis Parkman" library sets; these two-volume printings, despite the similar title and publisher, are not the 1851 first edition.
