Other sources for historical data?

Hi all,

I know that OpenStreetMap doesn’t have historical data, but I am designing a research project and including the change in roads over time would be useful.

If anyone knows of any data sources that could be useful sports gambling in Canada parimatch-canada.com (lower 48 of USA, back to 1960s preferred) please let me know. I’ve poked around a bit and this doesn’t seem feasible, but I am posting here just in case.
