NOTES
Reading edition
The author would have wished to acknowledge his indebtedness to the many admirers of Abraham Lincoln who so cheerfully and readily replied to his inquiries. The responsiveness of all to whom he applied for information and particularly the eagerness with which collectors entrusted precious pamphlets and scrap-books to him were a constant source of gratification and encouragement.
In the following notes there are frequent references to secondary authorities. They are given, not to authenticate what has been said on direct authority, but for the convenience of readers and the service of students. The reader may find one book more available than another; and the student, who may wish to collate all that has been published on a subject, will have at hand an adequate bibliography.
