ters 8 to 11, dealing with the period since 1897, which is
not covered in the _History of Labour_, the author used largely the same
sort of material as that in the preparation of the above named works;
namely, original sources such as proceedings of trade union conventions,
labor and employer papers, government reports, etc. There are, however,
many excellent special histories relating to the recent period in the
labor movement, especially histories of unionism in individual trades or
industries, to which the author wishes to refer the reader for more
ample accounts of the several phases of the subject, which he himself
was of necessity obliged to treat but briefly. The following is a
selected list of such works together with some others relating to
earlier periods:
