This site by Archer Software lists the extracted batch numbers for the British Isles that previously formed part of the International Genealogical Index (IGI). To search for a particular parish or church, click on the Country link at left (England, Wales, Scotland or Ireland) then on a County name. This displays an index of places (mostly parishes) with batch number, event type (birth, baptism, marriage), date range and other information. If you click on a batch number for a place (eg Ninfield, Sussex - Baptisms 1663-1879) a search box appears with the batch number listed, click on Submit to go to FamilySearch where the records for that batch number are displayed. There is the option to enter a Surname to display the FamilySearch records for that surname and place.
