From Quaker Dictionary
The Dictionary of Quaker Biography
The Dictionary of Quaker Biography was compiled jointly by Friends House Library, London and Haverford College Quaker Collection between the 1950s and 1980s. It consists of approximately 20,000 biographical entries on prominent British and American Friends from the 17th through the 20th centuries and amounts to about 32,000 typescript pages. There are two "original copies," one located at Haverford and the other at Friends House Library, London. Friends Historical Library at Swarthmore College has a photocopy of the Haverford "copy." The DQB gets frequent use in house at all three institutions and is cited often by scholars of both Quaker and non-Quaker topics in many reputable journals and monographs.
