The method of handling notes is not a makeshift device necessitated by the use of the old plates but it one that I have used in several previous books and found advantageous. In my opinion the text of a book should be written and presented for continuous reading. Calling the reader’s attention to footnotes merely distracts him. If he wishes to check up on the author or acquire additional information, he should do so at the end of the chapter by turning to the notes then. I have therefore constructed text and notes on what might be called parallel tracks, identifying the place of each note by means of the page reference and some significant words. In the case of quotations, I have given the first words in quotation marks.
