parish records contain a vast amount of administrative records, they cover the versty committee minutes, the constables accounts, the apprenticeship records, many overlap with the quarter sessions depending on the Parish. If you are just wanting Patish registers of christenings and marriages you can start with the IGI, it contains many Yorkshire parishes from 1537 - 1920s.
The actual Parish records will have been sent to the County Record Office in most cases, Wakefield has the CRO for the West Riding, some records that were originally in Richmond will be at the Lancashire Record Office at Preston, from previous questions I expect you will need Wakefield though.
