Use this form to send a reference inquiry to Manuscripts and Archives, or telephone the reference archivist at (203) 432-1744. All inquiries are answered in the order in which they are received. Depending on the volume of requests, a response may take two to three weeks.
Please provide as much information as possible about the subject of your inquiry, to assist us in focusing our research efforts on your behalf.
IMPORTANT: If you haven't done so already, please create an account for yourself in Aeon, our online registration and request system at https://aeon-mssa.library.yale.edu/ Registering will allow us to order collection material on your behalf from our off-site storage facility, if necessary, while we investigate your reference request.
Due to the volume of requests and staffing constraints, our reference staff can spend no more than one hour assisting patrons at a distance. Patrons who submit requests requiring more than one hour of staff time may choose to do the additional work in person or to hire a research assistant.
