Today was a busy day for launching records on both sides of the Atlantic. ScotlandsPeople released the 1920 Valuation Rolls. Like the other Valuation rolls, the images are 2 credits to view. A word of warning, the images are quite light, but seem to be more legible when you zoom in.
On this side of the Atlantic, Ancestry launched the now fully indexed 1921 Canadian Census. Apparently in an agreement with LAC, these will be free to anyone who logs on from a Canadian IP address. You need to have an account. You can create one for free.
