Reflections on Longmeadow
According to its Introduction: "Reflections is a mini-history if measured by its length, but its comprehensive although compressed treatment raises it to a level above the usual town history. Supplementing the readable and interesting text are many fine illustrations carefully selected from the Historical Society archives or kindly lent to the project by interested residents." This book was published in 1983 for the town's bicentennial and was co-edited by Mary Rogeness and Linda Rodger.
