Ireland's Representative Church Body (RCB) Library maintains a very special list, essential for family historian's researching Church of Ireland records, and updates it annually: 

THE LIST of CHURCH OF IRELAND PARISH REGISTERS

A Colour-coded Resource Accounting For What Survives;Where It Is; & With Additional Information of Copies, Transcripts and Online Indexes

As blogger Claire Santry explains, "Now running at 100 pages, the LIst details -- parish by parish -- the surviving and lost baptism, marriage, marriage and burial registers across the island, providing the years covered by each parish's volumes, and where researchers can access any manuscripts, digitised copies or transcriptions."

The December 2022 version of the List now includes the holdings of 1224 parishes and can be downloaded as a PDF.
