Special Collections

These collections are housed in closed stacks (except for the Dom Mocquereau Chant Microfilm Collection, which is located in the Microform Area). Because these collections contain material segregated from the general collection due to ephemeral nature, rarity, size, or other conditions, items within them cannot be found using SearchBox.
