Our collection contains a variety of historical documents, photographs, and artifacts related to Mary Baker Eddy and the history of Christian Science. The collection includes many “gems,” such as Baker family documents, reminiscences, and eight historic houses where Mrs. Eddy lived. Our staff strives to follow the highest standards of museum practice in the storage, care, and use of Longyear’s collection.

We regret that we are unable to accept research requests or accommodate on-site research visits at present. We look forward to serving you again later in the year.
