The fine art of correspondence: Jackie Robinson, the Kingsmen, Hunter S. Thompson.

The blog Letters of Note takes a closer look at correspondence we should know more about. Here are a few examples:

• A moving letter from baseball great Jackie Robinson to President Eisenhower: "17 million Negroes cannot wait for the hearts of men to change."

• Letter from W. J. Howard, assistant to the secretary of defense, listing four incidents where nuclear weapons went, um, missing
  

• A letter illustrating why the FBI investigated the Kingsmen's "Louie Louie"
  

• Something completely unprintable from Hunter S. Thompson
