Freedom, published in Harlem during the Cold War and McCarthy years, was Paul Robeson and Louis Burnham’s radical black paper that “ppenly challenged racism, imperialism, colonialism, and political repression and advocated for civil rights, labor rights and world peace”; NYU’s Freedom archive holds browsable (but not searchable, alas!) scans of issues with contributions from “W.E.B. Du Bois, Alice Childress and Lorraine Hansberry” and many others. (Thanks, Fipi Lele!)
