International Encyclopedia of Unified Science
In 1938 a new series of publications started in the USA, the International Encyclopedia of Unified Science (IEUS). An ambitious project and never completed, it was 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..." Only the first section Foundations of the Unity of Science (FUS) was published; it contains two volumes for a total of nineteen monographs published from 1938 to 1969.

Historian David Hollinger argued that the International Encyclopedia of Unified Science was a less comprehensive account of the sciences of the time than it could have been, and was especially weak in the social sciences. Hollinger noted: "The Encyclopedia of the Social Sciences (12 vols., New York, 1933–1937) was a prodigious endeavor brought to successful completion by Alvin Johnson. This encyclopedia is a much more important episode in the history of thought than The International Encyclopedia of Unified Science yet has attracted much less attention from historians than the abortive enterprise led by Neurath." Hollinger also said that the journal Philosophy of Science, founded in 1934, provided a much more inclusive perspective on the sciences in those years than did the International Encyclopedia of Unified Science.
American political theorist James Burnham refers to the Encyclopedia in Science and Style: A Reply to Comrade Trotsky (1940), his penultimate tract discussing his differences with Trotsky and marking Burnham's renouncement of dialectical materialism. In this text he responds to Trotsky's request to draw his attention to "those works which should supplant the system of dialectic materialism for the proletariat" by referring to Principia Mathematica by Russell and Whitehead and "the scientists, mathematicians and logicians now cooperating in the new Encyclopedia of Unified Science". Burnham resigned from the Workers Party three and a half months later declaring "that dialectical materialism, though scientifically meaningless, is psychologically and historically an integral part of Marxism" and that he had "for several years had no real place in a Marxist party."
