In 1938 a new series of publications started in USA. It was the
International Encyclopedia of Unified Science (volumes of which are titled
Fundamentals of Unified Science or FUS). An ambitious project never completed devoted to
unified science. It was an output of the
Vienna Circle to address the "growing concern throughout the world for the logic, the history, and the sociology of science..."
[citation needed]. Only the first section
Foundations of the Unity of Sciences was published; it contains two volumes for a total of twenty monographs published from 1938 to 1969.
