The Skilled Labourer, 1760-1832 (Barnes & Noble Digital Library)

In this 1919 volume, the final installment in a pioneering trilogy that began with The Village Labourer (1911) and continued in The Town Labourer (1917), the authors focus on the obsolescence of skilled labor in the face of technological change during the Industrial Revolution.  As in the previous two works, the Hammonds view their subject through a lens of class exploitation.
