The Past Speaks

I absolutely loved this EH. Net Encyclopedia article, which is about the history of the bar code. Because the article deals with a technology we see in use every day, it is very suitable for teaching purposes.  The author of the piece is Stephen A. Brown, who also wrote Revolution at the Checkout Counter: The Explosion of the Bar Code (Cambridge: Harvard University Press, 1997), which was regarded by critics as a first-class piece of research in economic history and the history of technology.

This article ranks as 2 out of 7. Tomorrow, I will post about my favourite EH Net Encyclopedia article.
