The Religious Society of Friends (Quakers) is small by anyone's definition, with only about 300,000 members worldwide, but its impact has been widely felt. Unlike other historical dictionaries, the authors present a series of worldwide essays on Quaker theology, history, and practice as well as the lives of individuals who have made this faith their life. The entries prove the variety among Friends today and also gives a clear sense of unity despite their diverse membership and their periodic disagreements and divisions.
