My editor noticed a battle of the top 16 circulating books at the local library in Norfolk, Conn. That called to mind the glorious Tournament of Books, which has been presenting a bracket of the year’s best novels since 2005. I’ve enjoyed the ’90s weepies matchups that are accompanied by thematic March Sadness essays. Farmer Blake’s March Milk-It contest pits the cows of an Iowa farm against one another. Arizona State University runs an annual March Mammal Madness bracket (humpback whale is going head-to-head with Indian rhinoceros in the division featuring animals that appear on currency).
