The titles which follow by no means cover all that has appeared in print concerning the American Seymours, but those regarded as the most important have been selected. One of the chief reasons for presenting the list is to assure the reader that the author and editor have not neglected previous accounts, and that where their account or conclusions differ from some of those hitherto put forward, such differences are not attributable to ignorance of the assertions made by other writers.
