This is an up-to-date reference
work for all those involved in teaching or researching the history
of twentieth-century technology, as well as the serious general
reader. The core of each of the main entries is a technical description plus illustrations
and further reading. There are also about 30 longer survey entries
that that address broad questions of technological systems, such
as the context in which the various technologies were developed,
discussions of any controversies and schools of thought, comparisons
between different political and economics systems, and the various
ways in which different nations have attempted to make and apply
science and technology policies.
