The Spanish Collection comprises archives relating to the International Brigade, the Spanish Civil War and the Aid Spain Movement in Britain. The collection was established in 1975 with the donation of the archives of the International Brigade Association, an organisation formed by veterans of the British Battalion of the International Brigade on their return from Spain in 1939. The collection also contains archive material of mixed provenance which was collected by the International Brigade Association, or donated separately to the Library since 1975 spanning a period from prior to the start of the Spanish Civil War in 1936 to the present day. It includes papers of other organisations such as the Appeal for Amnesty in Spain, the International Brigade Dependants' Wounded Aid Committee, the Basque Children's Committee and the International Brigade Memorial Appeal Committee; papers relating to over two hundred of the British individuals who travelled to Spain as military or medical volunteers during the Civil War, including diaries, correspondence, sketches, poetry and photographs; a large collection of printed ephemera relating to the International Brigades and the Aid Spain movement; and a large photograph collection of mixed provenance, including many contemporary photographs taken in Spain during the Civil War.
In addition to this collection the Library also holds large collections of pamphlets and periodicals relating to the Spanish Civil War and the International Brigade.
