Minutes of the Byberry Philosophical Society which was formed in the early nineteenth century for the "acquisition and promotion of scientific knowledge." The group collected specimens of flora, fauna, minerals, and items of historic interest and eventually erected a building to hold the collection. Almost all of their members were Quakers, but this was not a condition of membership.

The Byberry Friends Association was a Quaker group which met monthly in Byberry, Pa, to hear papers on a variety of topics and to discuss issues of the day. This collection contains the records of the Friends Association of Byberry, 1900-1932.
