Although it is popularly assumed that the history of computing before the second half of the 20th century was unimportant, in fact the Industrial Revolution was made possible and even sustained by a parallel revolution in computing technology. An examination and historiographical assessment of key developments helps to show how the era of modern electronic computing proceeded from a continual computing revolution that had arisen during the mechanical and the electrical ages. This unique volume introduces the history of computing during the “first” (steam) and “second” (electricity) segments of the Industrial Revolution, revealing how this history was pivotal to the emergence of electronic computing and what many historians see as signifying a shift to a post-industrial society. It delves into critical developments before the electronic era, focusing on those of the mechanical era (from the emergence of the steam engine to that of the electric power network) and the electrical era (from the emergence of the electric power network to that of electronic computing). In so doing, it provides due attention to the demarcations between—and associated classifications of—artifacts for calculation during these respective eras. In turn, it emphasizes the history of comparisons between these artifacts. Topics and Features: motivates exposition through a firm historiographical argument of important developments explores the history of the slide rule and its use in the context of electrification examines the roles of analyzers, graphs, and a whole range of computing artifacts hitherto placed under the allegedly inferior class of analog computers shows how the analog and the digital are really inseparable, with perceptions thereof depending on either a full or a restricted view of the computing process investigates socially situated comparisons of computing history, including the effects of a political economy of computing (one that takes into account cost and ownership of computing artifacts) assesses concealment of analog-machine labor through encasement (“black-boxing”) Historians of computing, as well as those of technology and science (especially, energy), will find this well-argued and presented history of calculation and computation in the mechanical and electrical eras an indispensable resource. The work is a natural textbook companion for history of computing courses, and will also appeal to the broader readership of curious computer scientists and engineers, as well as those who generally just have a yearn to learn the contextual background to the current digital age. "In this fascinating, original work, Tympas indispensably intertwines the histories of analog and digital computing, showing them to be inseparable from the evolution of social and economic conditions.

As millions of people have been exposed to computing through the tremendous growth of microcomputers, there has developed an increasing appreciation of the history of data processing, which dates back many decades before the arrival of the computer. Stretching back to at least the 1860s, such early technologies as adding machines, punch cards, and the office appliance industry are now being recognized for their place in the history of the information processing industry. This work brings together a comprehensive list of sources that offer a general introduction to the literature of the industry. Divided into nine chapters covering topics and historical periods, the bibliography provides an annotated list of published materials describing both the history of the industry and significant items of general interest. Each chapter is introduced with a short review of historically important issues and comments on the literature, and contains contemporary publications as well as more recent material. To give the work a continuing usefulness, ongoing publications, such as computer magazines, are highlighted. Entries are grouped under nearly 100 subheadings, covering such material as contemporary descriptions of hardware and software of the past, seminal technical papers, industry surveys, programming languages, significant individuals and companies, and the role of Japan and microcomputing. All citations are annotated with a brief summary of either the work's contents or its historical importance, while two indexes provide both subject references and author citations. This bibliography will be an important reference source for courses in the history of data processing and business history, and a useful addition to public, college, and university libraries.
