The collection was amassed by Ms. Elaine Goselin, longtime volunteer with Arbor. Goselin collected all play bills, donor and membership material, newspaper clippings, play reviews, biographies of performers and so forth. Arbor theatre Company was started in Peterborough Ontario in 1976. John Plank was the first Artistic director.
