Also, don't worry about getting confused with numberings. That is Jo's fault. He was always renumbering and re-organising his works, making it a nightmare for musicologists to find their way around his oeuvres.
Perhaps we should start pestering Chandos again!
I'm afraid that I'm responsible for the Wikipedia catalogue, having sourced original work-lists dating from 1904 through to 1952. I've tried to make it as comprehensive and user-friendly as I can, including lost works, abandoned works, changes of opus number, scoring and changes of nomenclature...
