Ancestry have put up some Manchester/Lancashire parish records with images produced by permission of Manchester City Council.
They cover the Catherdral quite well (except for 1858 marriages when my 2x-gr grandparents were married, which are missing

) and other areas of Manchester, Salford, Bolton, Rochdale, Stretford and Trafford, Ashton-under-Lyne, Oldham, Leigh and Rossendale.
