Punctuation, hyphenation, and spelling were made consistent when a predominant preference was found in the original book; otherwise they were not changed.

Simple typographical errors were corrected; unbalanced quotation marks were remedied when the change was obvious, and otherwise left unbalanced.

Illustrations in this eBook have been positioned between paragraphs and outside quotations. In versions of this eBook that support hyperlinks, the page references in the List of Illustrations lead to the corresponding illustrations.

The indexes were not systematically checked for proper alphabetization or correct page references.

Footnotes, originally at the bottoms of pages, have been collected, renumbered sequentially, and placed just before the first Index.

The Catalog (“General List of Works”) pages at the end of the book have been renumbered to begin at 601, the title of its index has been changed from “Index” to “Catalog Index”, and the page references in that index have been renumbered accordingly. In the original book, only the parts of titles that fit on the first line were printed in boldface; this eBook attempts to include more or all of those titles in boldface.
