Series III. Miscellaneous contains a volume of minutes from the Columbian Manufacturing Society, an exercise book belonging to an unidentified person, non-Stark correspondence and miscellaneous papers. Also included in this series is a folder with photocopies of documents housed at the New Hampshire Historical Society relating to John William Stark, which were made in 1992 (it is unclear who made these or why they were added to the collection). There are also unused book plates from Donald Bloch's collection.
