The First World War had a revolutionary and permanent impact on the personal, social and professional lives of all women. Their essential contribution to the war in Europe is fully documented in this definitive collection of primary source materials brought together in the Imperial War Museum, London. These unique documents - charity and international relief reports, pamphlets, photographs, press cuttings, magazines, posters, correspondence, minutes, records, diaries, memoranda, statistics, circulars, regulations, and invitations - are published here for the first time in fully-searchable form, along with interpretative essays from leading scholars. Together these documents form an indispensable resource for the study of 20th-Century social, political, military, and gender history.
