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.
