 in an alphabetical list at the close of the book. Anonymous books 

 and tracts are indicated by quotation marks. 



I owe thanks without measure to Professor Clive Day for his 

 extensive assistance in the preparation of this work. His guidance 

 has been constant and inspiring and careful. He has been indulgent 

 of my faults and patiently criticized in a stimulating way both the 

 plan and content of the book. To him I tender my deepest thanks. 



My thanks are due to Professor Charles McLean Andrews for 

 having read the manuscript in a preliminary stage and given me 

 most valuable criticisms and suggestions. 



Messrs. Henry R. Gruener and Henry Ginter and the members of 

 the economics division of the Yale Library staff have been very 

 courteous and helpful. I thank them greatly.
