Translations are a rich source of science and social science information, but they can also be hard to track down. Many translations were produced in the mid-twentieth century, partly in response to growing interest in scientific and technological developments outside the U.S.
Databases and full text online sources have improved the search process, but sometimes print indexes must be consulted, especially for work supported with U.S. government research contracts.
Some fields have developed discipline specific indexes for translations. Here are a few suggestions.
Nuclear Science, Atomic Energy
Published for EURATOM, European Atomic Energy Community, covers 1962-1977 and includes related fields such as chemistry, physics and materials science. These don't appear to be included in the CITE indexes.
