[2][3] Distributed by a Swiss foundation, the newsletter was created because mainstream academic journals were reluctant to publish articles about the philosophy of quantum mechanics, especially anything that implied support for ideas such as action at a distance.

[4] Articles questioning the mainstream position were therefore distributed in alternative publications, and Epistemological Letters became one of the main conduits.

[12] Don Howard, Professor of Philosophy at the University of Notre Dame, was a Ph.D. student of Abner Shimony, one of the editors of the newsletter; as such, he had an almost complete set.

In collaboration with Sebastian Murgueitio Ramirez (then his graduate student, now assistant professor of philosophy at Purdue University), the set was completed and digitized in 2018–2019, in order to make this very rare document available to the community of historians and philosophers of physics.

The entire set is available to the public at the Epistemological Letters digital archive, and the original newsletter is in Special Collections at the University Library.
