Despite the humble origins of its name (Anglo Saxon for "the speck at the head of a boil"), the dot has been one of the most versatile players in the history of written communication, to the point that it has become virtually indispensable. Now, in On the Dot, Alexander and Nicholas Humez offer a wide ranging, entertaining account of this much overlooked and miniscule linguistic sign.

The Humez brothers shed light on the dot in all its various forms. As a mark of punctuation, they show, it plays many roles--as sentence stopper, a constituent of the colon (a clause stopper), and the ellipsis (dot dot dot). In musical notation, it denotes "and a half." In computerese, it has several different functions (as in dot com, the marker between a file name and its extension, and in some slightly more arcane uses in programming languages). The dot also plays a number of roles in mathematics, including the notation of world currency (such as dollars dot cents), in Morse code (dots and dashes), and in the raised dots of Braille. And as the authors connect all these dots, they take readers on an engaging tour of the highways and byways of language, ranging from the history of the question mark and its lesser known offshoots the point d'ironie and the interrobang, to acronyms and backronyms, power point bullets and asterisks, emoticons and the "at-sign."

Playful, wide-ranging, and delightfully informative, On the Dot reveals how thoroughly the dot is embedded in our everyday world of words and ideas, acquiring a power inversely proportional to its diminutive size.

"Ideal for etymologists and trivia buffs, this book covers an array of information and innovations on the relevance of this speck, from the preDewey decimal library of Alexandria to the modern global culture of URLs, instant messaging and the music of Stevie Wonder." --Publisher's Weekly

"In the emendations of proofreaders, the computer coding of internet engineers, the calculations of accountants, and the musical notations of composers, the Humez brothers catalogue an impressive array of meanings conveyed by the dot. The author's lively inquiries open surprising political and literary insights. Who would have guessed, in short, that a mere speck of ink could inspire such a fascinating foray?" --Booklist
