This list does not include hundreds of works alluded to, and often named in the text, but not specifically cited. It is virtually confined to those works for which specific credit appears in the footnotes. The works are classified under three headings: books, periodicals and other serials, and manuscript material. PFF1 953.1
Because of the extraordinarily large number of sources and authorities listed in the Bibliography, book and periodical titles, with accompanying references, are not repeated in the Index; the page references for the works cited therefore appear only in the Bibliography. PFF1 953.2
