Nifty little tool for those fond of reading reprints of old catalogs: The Inflation Calculator.

Before you decide that it was "the good old days" when you could buy a man's suit for $5, give the little algorithm on The Inflation Calculator a whirl.

(Also useful for when you are reading Nero Wolfe novels and see that it takes $1000 or thereabouts per month in 1948 to run the Brownstone...you can translate it into "modern day" dollars and see that it's closer to $10,000 now)
