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".

This collection includes both the printed and hand-coloured maps produced by the inquiry. Further topics addressed in Booth's papers and notebooks include industry and religion.
