Because of the rarity of the collection, materials do not circulate and books are not available through inter-library loan. The stacks are closed to the public, but staff members will readily assist visitors with their requests. Photocopies of materials are available for a fee, and in-house photographic services are available. Extensive research can be arranged through the librarian.
