I know a lot of work is still going on with respect to the summer era, but given how complicated it will be, I think it might not be a bad idea to keep progressing work on earlier years at the same time behind the scenes.
A particular issue is WW2 guest players. Leeds had well over 100 guests during WW2, and I imagine similar will be true for most clubs that kept running. I have identified most of the guest players for Leeds, including first names, source clubs etc but there are a number of question marks. Just today thanks to the Huddersfield Heritage guys I think I've identified the first name of a player supposedly from Huddersfield but who was most likely in turn a guest at Huddersfield from Batley.
Given that the spreadsheets we send back to the RKC do not include all these details, how are they being captured, and how do we try to QA such that we can be as sure as possible that we are correctly identifying players?
