This used to be the height of my Family History year, when I learnt about all sorts of records becoming more accessible. Putting it online does offer remote users the chance to find out more.
I note that one of the sources is something I'm fairly sure used to be indexed on card, and I used right at the start of my visits to the then PRO, before the cards seemed to disappear. Looking forwards to discovering whether that is the case!
