Language of the Streets

In 1938, jazz bandleader and singer Cab Calloway published the first dictionary by an African-American, Cab Calloway's Cat-ologue: A "Hepster's" Dictionary, which became the official jive language reference book of the New York Public Library.

In 1939, Calloway published an accompanying book titled Professor Cab Calloway’s Swingformation Bureau, which instructed readers how to apply the words and phrases from the dictionary. He released several editions until 1944, the last being The New Cab Calloway’s Hepsters Dictionary: Language of Jive.

Poet Lemn Sissay observed that "Cab Calloway was taking ownership of language for a people who, just a few generations before, had their own languages taken away."
