The first subgroup (1976-1979 Accessions) is divided into seven series: Correspondence, Manuscripts and Writings, Public Statements and Publicity, Biographical Material, The Republic of New Africa, The Crusader, and "Radio Free Dixie" Transcripts.
The Correspondence series (1956-1979) consists primarily of incoming personal, political and legal correspondence. Topics covered range from international political theory to Williams legal status. Correspondents include attorney Conrad Lynn, various political compatriots, academics, students, and members of the press.
The Manuscripts and Writings series (1961-1970) consists primarily of article and book manuscripts, and includes some published articles by, and interviews with, Williams. The series also contains several books authored or co-authored by Williams.
