A few references are from unpublished registers but most are from the series of indexed volumes published by the Parish Register Section of the Yorkshire Archaeological Society, with 180 titles. Sheffield has seven volumes and in this case the reference includes the vol. no. and page. Registers published by the Thoresby Society are Aberford, Adel, Methley and Leeds. The early Bradford registers are printed in The Bradford Antiquary (see BAS) and a few others have been privately printed. It should be noted that some references under PR are from published registers which contain church wardens accounts, deeds, wills etc. as in Clay, J.W. The Registers of Elland 1559-1640, Leeds (n.d.) and Margerison, S. The Registers of the Parish Church of Calverley 1574-1720, 3 vols, Bradford (1880, 1883, 1887). The extra material in the Kirkburton register is very full and has been given the abbreviation FAC.
