When you find a book that is relevant to your topic, ALWAYS check the bibliography for other sources. It is likely that you can use many of the sources that the author of your book has cited.
On this page, you will find specific titles and links to e-Books that may be helpful. Some links will direct you to the online NOBLE catalog with a link there to use the e-Book, while others go directly to the print book scan in the Internet Archive. Remember that you can't judge a book by its cover - - browse the Table of Contents and Index of any book here to look for source material, or conduct your own searches for e-books on the next page of this guide.
