This brief note introduces the Elizabeth Roberts Working Class Oral History Archive, which is based at Lancaster University and Lancashire Archives. The archive was created by the highly influential oral historian Elizabeth Roberts in the 1970s and 1980s, when she undertook extensive and wide-ranging interviewing programmes in Lancaster, Preston and Barrow-in-Furness. These are now recognised as of national importance, as one of the key oral history collections of the twentieth century. They are now available online, and this article describes the procedures for digitising the archive material, access and searching the material, and its research potential.
