[Vision2020] Adjustment for inflation

[Mushroom]

This will seem strange, but my question has nothing to do
with funding for public schools -- although I think the
question of adjusting for inflation has come up in
connection with posts about funding public schools.

Could someone point me toward a table which would allow
adjusting for inflation over the past 60 or 80 years? One
formula obviously won't do, because the rate has varied.

I'm sure there are different tables based on prices for
different things, but I'm not picky as long as a source can
be associated with the table
