The Mary Baker Eddy Library collections contain letters, manuscripts, photographs, objects, books, periodicals, and other materials.
Our collections are divided into three main areas:
- The Mary Baker Eddy Collection (comprising Eddy’s manuscripts, correspondence, printed materials, scrapbooks, and diaries)
- The Library Special Collections (including The Mary Baker Eddy Collection)
- The Organizational Records of the The First Church of Christ, Scientist (an active and growing body of material documenting many facets and activities of the Church and the Christian Science Publishing Society)
Portions of these collections are digitized and available to patrons on-site, in both of our research rooms.
Online researchers may search our reference collection through the online catalog.
For access to Mary Baker Eddy’s manuscripts, please visit mbepapers.org. This website is constantly adding new content. It currently includes annotated transcriptions and scanned documents from 1872 through 1884.
To assist researchers, our staff has generated the following list of finding aids and guides. These only outline the resources the Library offers.

Historic Bible Collection, c. 1530-2007
The Historic Bible Collection began to take form in the 1930s, when a Christian Scientist in England donated a number of rare Bibles to The Mother Church in Boston. The Christian Science Board of Directors’ original criteria for adding to the Bible collection were “editions which indicate steps in the history of mankind or which have been of great benefit or value to a large number of people.” Rather than simply unusual or rare, the Bibles needed to “represent turning points in history.” This collection now numbers 465 volumes. It includes first editions of the Coverdale, Matthew, and King James Bibles, as well as historic Bible reference, devotional, and related books. View a selection of Bibles from this collection.
