Footnotes have not had it easy. Their dominance of eighteenth- and nineteenth- century literature and scholarship was both hard-won -- following many years of struggle -- and doomed, as it led to belittlement in the twentieth century. In <I>The Devil's Details,</I> Chuck Zerby playfully explores footnotes' long and illustrious history and makes a clarion call to save them from the new world of the Internet and hypertext. <P> In a story that boasts a marvelous plot and a rogues' gallery of players, Zerby examines traditional footnotes and their less-buttoned-down incarnations, as when used by pornographers. Yes, <I>The Devil's Details</I> is full of surprises: Zerby hunts down the first bona fide fully functioning footnote; unearths a multivolume history of Northumberland County, England, that uses one volume for a single footnote; and uncovers a murder plot. He even explains why footnotes are like blind dates. <P> Carefully researched and highly opinionated, <I>The Devil's Details</I> affirms that delight in reading can come from unexpected places.
