Britain's first-ever account of black journalism was launched at the NUJ Annual Delegates Meeting.
A Century of Black Journalism in Britain, 1893-2003 covers both the black press and the contribution of black journalists to the national and regional press as well as broadcasting.
The book's author, Lionel Morrison OBE, was the union's first black president and is chair of its black members' council.
Born in South Africa, Morrison was arrested in 1956, along with 155 other dissidents including Nelson Mandela, for his part in resisting the Apartheid regime.
The book contains a series of his articles and talks on diversity and racism in the media and tells of the "persistent struggle against widespread prejudice, racism and discrimination mirrored by stereotyping and rejection in the conventional media".
