Chapter II has three types of footnotes, with different notations.

References to the author's previous book, being short, are placed at the end of the paragraph; numbered technical or tabular footnotes, or footnotes referencing other publications are collected at the end of the Chapter, before the Chapter Bibliography; and Chapter Bibliography footnotes are placed at the end of the Chapter Bibliography. In later Chapters, numbered footnotes are placed either at the end of the Chapter (before the Bibliography) or at the end of a relevant section of a Chapter.
