To Make a Poet Black [PDF ebook] 

This classic study of American Black poetry, first published in 1939 and long out of print, is the work of perhaps the pre-eminent figure in Black Studies of the past two generations. A major contribution to the history of Black thought in America, it ranges widely, beginning in the late eighteenth century with Jupiter Hammon, the first American Black writer, and ending in the 1930s with Countee Cullen and Langston Hughes.
