A classic book that is often cited in studies of the history and social impact of technology is Sigfried Giedion's 1948 Mechanization Takes Command. Lucky for us the always-excellent New York Review Books is bringing it back into print (March 2010). From the description:
Sigfried Giedion's extraordinary, encyclopedic book traces the various
ways in which, for better and for worse, mechanization has assumed
control of our lives, from modern systems of hygiene and waste
management, to agricultural production, fashion, and beyond.
book is not only clearly written but also eloquent and thoughtful in
its investigation of mechanization's reach and appeal, and it offers
fascinating insights into the intersection between mechanization and
the imagination, as manifested in literature and the visual arts. With
a wealth of unusual and intriguing illustrations taken from old sales
catalogues, industrial manuals, magazines, and other sources, Giedion's
book constitutes a remarkable and endlessly suggestive history of
modernity itself, as comprehensive as it is provocative and eccentric.
