Research & Reference Services
Research & Reference Services provides access to original materials that document the life of Mary Baker Eddy and the church she founded. The collections are central to the Library’s mission and include letters, manuscripts, organizational records, photographs, artifacts, books, periodicals, audiovisuals, and other materials available for in-depth research.
The Research & Reference staff welcome your questions about Mary Baker Eddy and the history of the Christian Science movement. We will also be happy to answer questions about your visit to the Library. Depending on the question, a response may be given immediately; in other instances, additional time may be required. Due to the heavy volume of inquiries, it may take up to 6 weeks to respond to a question. There is no charge for this service beyond copy costs, if applicable.
