Archives holding material on the British volunteers in Spain

Within Britain, there are a number of archives holding material on the British volunteers in Spain. 

The main collection of the International Brigade Association (now part of the IBMT) is at the Marx Memorial Library, London. It includes documents compiled by various members of the battalion in Spain, memoir material, photographs and material relating to the work of the IBA after the defeat of the Spanish Republic. The MML has an online searchable catalogue.

The Imperial War Museum in London contains some collections donated by individual volunteers such as Fred Copeman, one of the commanders of the battalion in Spain. There are a large number of detailed and lengthy interviews with volunteers from the UK and beyond, from both the Republican and Nationalist sides, which are held in the Imperial War Museum Sound Archive, an annex to the main building in London.

Also in London is the Public Record Office in Kew, which apart from the mass of material on the British Government's responses to the war, also contains various details relating to volunteers such as their imprisonment and repatriation. The online catalogue can be searched on-line.

The People's History Museum in Manchester has a number of photographs, plus a lot of material from the Communist Party, including Harry Pollitt's papers. There  is also an important Spanish Civil War Collection at the Working Class Movement Library, in nearby Salford.

There is a large holding, focusing on Welsh volunteers, in the Spanish Civil War Collection, in the Swansea Miners' Library, Swansea, and AJEX in London contains details of Jewish volunteers from the UK.

There are several important collections held outside the United Kingdom. The most significant are ALBA (the Abraham Lincoln Brigade Archive) in New York and the International Brigade Collection, Russian Centre for the Preservation and Study of Recent Historical Documents in Moscow. There are also, of course, important archives in Spain itself, including the Archivo General Militar de Avila, in Avila and the Military Archive in Salamanca.
