Some names marked ", passim" occur too frequently to index completely.
Tables are referenced by the letter "t" and the table number.
Figures are referenced by the letter "f" and the figure number.
The text refers to sources by one or two authors' names, e.g.: "Fant et al. (1974)" or "Stevens and House (1955)" so the names of additional authors are not indexed here. These same sources are listed in the SSSHP pages where all authors are indexed.
