Encyclopedia of twentieth-century technology

Comprising 440 essays arranged alphabetically, mostly on individual objects, artifacts, techniques, and products, this is an up-to-date work of reference for all those involved in teaching or researching the history of 20th-century technology, as well as the serious general reader.

The core of each of the main entries is a technical description, within a historical narrative, of about 1000 words plus illustrations and further reading.

There are also about 30 longer survey entries 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.
