BBC Information and Archives (sometimes known just as BBC Archives) are collections documenting the BBC's broadcasting history, including copies of television and radio broadcasts, internal documents, photographs, online content, sheet music, commercially available music, press cuttings and historic equipment. The original copies of these collections are permanently retained but are now in the process of being digitised, estimated to take until approximately 2015. Some collections are now being uploaded onto the BBC Archives website on BBC Online for viewers to see. The archive is one of the largest broadcast archives in the world with over 12 million items.
