Finding Church of Ireland baptisms, marriages and burials

There are 98 pages in this closely spaced table listing, parish by parish, the years for which some form of record for Church of Ireland baptisms, marriages and burials are available.
It's available at http://ireland.anglican.org/cmsfiles/pdf/AboutUs/library/registers/ParishRegistersTable.pdf but you might want to start at http://ireland.anglican.org/about/168 which includes information on some digitised records.
John Grenham's most recent Irish Roots column Resurrecting Church of Ireland records has additional background.
