This long-awaited addition to the existing well established nine-volume Dictionary of Labour Biography is organised on a self-contained basis. The time-span of the tenth volume covers the period of modern industrialism, from the late eighteenth century to the present. Living people are excluded. It is intended to include anyone who was active, at any level, in the organisations and institutions of the British labour movement, as well as those who influenced the development of radical and socialist ideas. Entries are on the same pattern as those for the Dictionary of National Biography , but with many more bibliographical sources provided.
