The collection centres on materials relating to the activity of the Trotskyist International Spartacist Tendency in Britain. The collection covers 3 periods:
1964-1975: The Spartacist Tendency had no permanent organised presence in Britain during this period. However the publications of the Spartacist League/US Spartacist and Workers Vanguard contain many articles referring to the general political situation in Britain, and to British socialist parties and groups. In particular Spartacist contains much material in the 1960s on the Healy tendency (Socialist Labour League), and Workers Vanguard has extensive coverage of the 1974 miners' conflict with the Heath government.
1975-1978: The London Spartacist Group (LSG) was active during this period. From 1975 Workers Vanguard has been distributed widely on the British left, both through subscriptions and single-issue sales. In this period the LSGs activity is reported and reflected in that paper, and also in various mimeographed leaflets included in the deposit.
March 1978 to the present: At the beginning of this period the Spartacist League/Britain (SL/B) was founded in a fusion between the LSG and the Trotskyist Faction (TF) of the Workers Socialist League. The TF had been formed as an internal faction in 1977, and resigned from the WSL in February 1978. In April the first issue of Spartacist Britain, the monthly paper of the SL/B, was published (in September 1984 the name was changed to Workers Hammer). In 1980 the Leninist Faction of the WSL fused with the SL/B, and in 1981 the Communist Faction of the IMG did likewise. Materials relating to these two groups are included in the deposit, in addition to the newspapers, journals and leaflets of the Spartacist Leagues itself.
The collection comprises: Spartacist Britain / Workers Hammer, issues 1-165, April 1978-August 1991; Workers Vanguard, Spartacist Publishing Company, New York, issues 33-408, 1976-1986; miscellaneous publications and leaflets, 1964-1983.
