For those of you who have read Georges Ifrah's first book,
The Universal History of Numbers: From Prehistory to the Invention of the Computer, this is the third of a two-volume set! Just to clarify this, the first volume is being split into two and, together with this new third volume, republished as a trilogy. For those of you who have not read the first book, volume III begins with what could have been a very useful "Chronological Summary" and a "Recapitulation" of the ideas expressed in the first book. Unfortunately, without a preface or introduction, the unwary reader is immediately confronted with a very condensed version of the first book. Indeed, Ifrah's detailed study of number systems, when reduced to a series of illustrated plates, gives the impression that the history of numbers is little more than a history of typography. Yet another "Chronological Summary" from Calculation to Calculus follows, thereby reinforcing the feeling that the book is a collection of notes waiting to be crafted into a strong narrative. The translator, the unsung hero in many publications, has done sterling work in adding copious notes and helpful cross-references. The initial feeling remains, however, that this is a collection of jewels without a crown.
Having said that, the scope of the book is enormous, tracing the history of calculators and computers, from mechanical to electronic devices through both analogue and digital incarnations. There are some familiar faces, such as Pascal, Babbage, von Neumann and Turing, as well as many others who have so far escaped the spotlight. As a reference work it has a good index and an extensive bibliography. The author acknowledges regret at the lack of illustrations but gives references to such sources. In the search for universality and completeness it has, however, forsaken a strong guiding theme. The most engaging sections are where the mathematics, history and technology come together, bound by personal ambitions, whether intellectual or financial. In such sections Ifrah pauses from being a cataloguer to indulge in some story telling. It is here that the nuts and bolts of technology come to life. For teachers, students and researchers, this will prove to be a very useful starting point into a fascinating area of human innovation. But one would venture that this is a work destined for the library shelves rather than the bedside table. --Richard Mankiewicz

From Kirkus Reviews
Ifrahs monumental follow-up to From One to Zero (1993) goes from one to (almost) infinity as he meticulously reviews the numbers and reckoning systems of countless tribes and cultures in a dazzling scholarly performance. ``Performance'' is the operative word here, for not only does Ifrah enumerate the words and symbols used for arithmetic, but he also explains how to use each system, providing illustrations, diagrams, riddles, and puzzles. Indeed, nearly every page displays handsome numerals, counting devices, and illustrations of their use. Ifrah takes the human body as the aboriginal point of reference for most counting systemsfingers and toes producing systems using 5, 10, or 20 as a base. But 12, 60, and 360 have also been used, usually by cultures that attached more importance to the sky than to their anatomy. Ifrah gives special credit to the Mayans for their extraordinary adeptness at astronomical measurements, which calculated the length of the solar year as 365.242 days and the month at 29.53086 days. He commends India for the invention of zerothe placeholder in counting systems that use positional notation to indicate the different values, for instance, of 1, 10, and 100. A recurring theme is the intimate relation between number systems and written language. Just as the invention of alphabets allows the generation of myriad words, advanced number systems can use a limited number of symbols to represent any large number. A quibble or two: Ifrah frequently asserts that our brains cannot instantly number a collection of more than four objects, though psychologists maintain we can recognize up to seven objects without counting. And since many statements on the origins of systems and borrowings across cultures are speculative, they are subject to change in light of recent discoveries. A must for any libraryand a wonderful gift for anthropologists, ethnographers, cultural historians, and quiz kids.
