The original index, with some slight unavoidable changes of typography, is reprinted as it appeared in the third, fourth and fifth editions, but I have added to it, in square brackets, a large number of new articles and references. I have endeavoured by these additions to make it absolutely complete in regard to names of places and persons, except that it seemed useless to include the names of kings and others when used merely to indicate dates, and altogether vain to hope to deal comprehensively with 'Asia,' 'England,' 'Great Britain' and 'Europe'. I have inserted a few catchwords which may aid in the recovery of particularly striking passages, such as 'Invisible hand,' 'Pots and pans,' 'Retaliation,' 'Shopkeepers, nation of'. I have not thought it desirable to add to the more general of the headings in the original index, such as 'Commerce' and 'Labour,' since these might easily be enlarged till they included nearly everything in the book. Authorities expressly referred to either in the text or the Author's notes are included, but as it would have been inconvenient and confusing to add references to the Editor's notes, I have appended a second index in which all the authorities referred to in the text, in the Author's notes, and in the Editor's notes are collected together. This will, I hope, be found useful by students of the history of economics.
