Welcome to The Mary Baker Eddy Library

Since opening to the public in 2002, the Library has offered a place to explore the life, ideas, and achievements of Mary Baker Eddy, who discovered and founded Christian Science—a pioneer whose work touched the fields of religion, health, and journalism. 

The Library houses a rich and extensive collection of original materials that includes documents, art and historic artifacts, photographs, books, and audiovisuals that document the history of the church she founded, up to the present day. 

Explore this website to learn about the Library’s programs, podcasts, exhibits, and archives. Ask us your questions…and read about our research.
