The library was founded in 1967 as the Eastern Pennsylvania Mennonite Historical Library. Members of the founding committee were John Fretz, Ray Hacker and Marvin Rosenberger of Eastern District Mennonite Conference, and Ernest Clemens, Nevin Moyer and Wilmer Reinford of Franconia Mennonite Conference.


The library is open Tuesday to Friday, 10 am to 5 pm and Saturday from 10 am to 2 pm. We suggest that you schedule your library visit with collections manager Joel Alderfer (215-256-3020, ext.111) to ensure that he or archivist Forrest Moyer will be able to assist you.


Members of the Mennonite Historians of Eastern Pennsylvania are admitted to the Library free. Anyone may join the MHEP. Non-members who wishes to access the library or collections will be charged an admission of $5.00 per day.  Full time students are admitted free.
