Practically all the important books of reference on the subject are mentioned in the text. A Bibliography of books and magazine articles, up to 1914, will be found in C. Bertrand Thompson's collection of papers published under the title of "Scientific Management." This collection includes many original documents otherwise difficult to obtain, and forms an excellent historical sketch of the subject, considered as a movement. H. B Drury's "History and Criticism of Scientific Management" appeared in 1915, and was followed in 1916 by R. F. Hoxies "Scientific Management and Labour," for the most part very searching criticism.
