There is only one older such center in North America, and that is the University of Minnesota's Center for Philosophy of Science, which was founded in 1953 around Herbert Feigl.
Beginning in 1963, the proceedings of many colloquia were published in the series Boston Studies in the Philosophy of Science (first by the D. Reidel Publishing Company, then by Kluwer Academic Publishers, Dordrecht, and now by Springer) [REF].
