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.

Research services

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 six weeks to respond to a question. There is no charge for this service beyond copy costs, if applicable.

Mary Baker Eddy Papers project

Since its opening in 2002, the Library has made available the personal papers of Mary Baker Eddy through its Research Room. Scholars, church members, and other interested visitors have had to come to Boston to access the more than 28,000 letters and manuscripts written by Eddy or her secretaries on her behalf. Now, with the Mary Baker Eddy Papers pilot project, the Library is bringing a first selection of these documents to you by making available online Mary Baker Eddy’s sermons and related documents. Learn how to best navigate the Mary Baker Eddy Papers with this video tutorial. Explore these selections from the Mary Baker Eddy Papers: Enter Site
