In 2010, the PHS Publications Committee produced its 30th annual Occasional Paper.
Written by Dennis Carter–Edwards, it tells the story of 19th century mapmaker David Thompson, his son-in-law George E. Shaw, and their connection to Peterborough.
The annual Occasional Papers are distributed to PHS members as a membership benefit. They are also available for sale in the Hutchison House bookshop and through the PHS Office.
From time to time, PHS also produces books. The book grew out of her PHS Occasional Paper about Fleming, No Better Inheritance, published in 1990, which involved transcribing Fleming's original diaries, now held in the Library and Archives of Canada.
The book was edited by Jean Murray Cole, a long time member of PHS and its Publication Committee. Jean began promoting the idea of publishing this book in the mid 1990s and spent countless hours pouring over the original diaries at the Library and Archives Canada. Fleming is included among Peterborough's early celebrities. Dr. Hutchison was his father's cousin and Fleming was a frequent house guest of the Hutchisons during his first two years in Canada, after immigrating in 1845, at age 18.
