To avoid the use of footnotes or reference numbers within the text, the key, which follows the text, is provided as a guide to the numbered references in the Bibliography. For each section of each chapter the reader will find appropriate identification of material in the text, along with a number to indicate the source from which it is drawn. Wherever possible I have used the original source material; when this has not been possible, and I have used a secondary source in which the original material has been cited, then the reader will find that the key number is italicized. |
