Beatrice Webb & Sidney Webb 
The History of Trade Unionism (Revised edition, extended to 1920) [EPUB ebook] 

The author of this British book states that 'The reader must not expect to find, in this historical volume, either an analysis of Trade Union organisation, policy, and methods, or any judgment upon the validity of its assumptions, its economic achievements, or its limitations.’ The book instead explains how, since the original publication of the book in 1890, the trade union movement has grown to encompass 60% of all workers, and how it may now form the foundation for a new political party.
