Comments and elaborations are welcome. And when I say footnotes, I include endnotes. Footnotes are comments by various editors who had rejected the manuscript. Foundation , Foundation and Empire and Second Foundation by Isaac Asimov. The Mezzanine , Nicholson Baker .
Footnotes annotate the gospel the characters seek.
Has an index, too. The Testament of Yves Gundrun , Emily Barton. American Hero , Larry Beinhart. Not just footnotes and indices, I'm told, but charts, graphs, photographs, and a six-page bibliography. Ficciones , Jorge Luis Borges .
