The collection assembled by William Morse reflected his research interests and his ideas on what works should be available for consultation by serious scholars. The exploration and early settlement of Acadia, the history of the Maritimes, the evolution of printing, the book arts, important classics in both the humanities and the sciences, the works of Bliss Carman and George Santayana, works about General James Wolfe, and Norse legends are the major research fields represented in the collection.
