A collection of papers and publications produced by the Fabian Society between 1884 and 2009, including the Fabian Tracts, the Young Fabian pamphlets series and meeting minutes. These materials provide a record of the Society’s internal administration, as well as illustrating their political and ideological evolution over time. Founded in 1884, the Fabian Society is a prominent left-wing think tank which has had (and continues to have) a significant influence on the British left, most notably the Labour Party. The Society was founded with the purpose to "reconstruct society in such a manner as to secure the general welfare and happiness".

A curated collection of material relating to the development of left-wing politics. The collection begins with material relating to the assassination of Italian socialist MP Giacomo Matteotti, and will soon also include material relating to the development of British labour such as the Independent Labour Party.
