Many archive and special collections at Senate House Library chart the history of left-wing, alternative and radical political movements. Of particular interest are the personal papers of Trotskyist activists (e.g. Alan Clinton, Will Fancy, Juan Posadas).
Furthermore, many and diverse aspects of the history and development of the working class movement can be explored through the Heisler, Higgins/Richardson, Burns and Pelling collections, which in some cases include both archive and printed special collection material. Pacifism as a form of social and political activism in the earlier part of the 20th century is another subject also represented in the archive and special collections holdings at the library.
Senate House Library also holds a wealth of material relating to queer culture and activism, from the literary to the campaigning for LGBT+ rights and equality. Of particular significance to SHL is the personal library of Jonathan Cutbill, a prominent LGBT campaigner and Britain’s foremost collector of books of LGBT relevance.
