Chapters in Scholarly Books
NOTE Re Chapter Above: References from the 26 chapters in the book above were intermingled in a single Reference section at the end of the book. References from our manuscript are appended to our chapter above in uneven pages, because they began near the bottom of page 18 of the manuscript and each page was numbered. To avoid possible confusion by showing that partial last page of text and by showing page numbers, the pages were trimmed accordingly.
