The initial deposit, sections A-K, consists mainly of correspondence and associated papers (leaflets, memoranda, extracts from minutes, etc.). There are two main series of correspondence: 'People' and 'General' and some other distinct smaller series such as 'Branches and other Societies'. The internal arrangement of these files is normally chronological, with a few exceptions (usually an alphabetical arrangement). There are also lecturers' report sheets, publications, slides, posters, charts, and photographs, mainly but not exclusively in Section G: Propaganda and Publicity. There is a set of Annual Reports and related material 1908-1979 (Section A). Under the will of Dr. Marie Stopes the Eugenics Society was left her birth control clinic, books from her library and certain emoluments. Three boxes of her correspondence and some miscellanea, were assigned to section K. In 1988 minute books and the Society's extensive collection of press cuttings plus some financial records were added as GB0120 SA/EUG/L-N.
