The Presbyterian Historical Society was founded in 1907 to promote public awareness of the history of the various strands of Presbyterianism in Ireland. Once described as a ‘Treasure House of Ulster’s History’, the Library of the Presbyterian Historical Society contains some 12,000 books and pamphlets.
The collection includes a large number of congregational histories. Manuscript materials include session minutes, baptisms and marriages from individual churches. The society also has a duplicate set of the microfilm copies of Presbyterian Church registers held by the PRONI covering the vast majority of congregations in Ireland.
