According to a mention in Garrison Keillor’s writer’s almanac, today is the birthday of Melvil Dewey.
This prompted me to look at the middens of paper around me, and think about Dewey’s invention of the vertical filing cabinet. Thinking turned into procrastination. Instead of putting those papers into those filing cabinets, I turned to Google. I found this book review: The social life of paper. Also see the short biographical entry in Wikipedia.
