Participating presses include University of Illinois Press, Indiana University Press, Michigan State University Press, University of Minnesota Press, University of Nebraska Press, Northwestern University Press, The Ohio State University Press, Penn State University Press, Purdue University Press, University of Michigan Press, and University of Wisconsin Press.

This collection has established a model for unified, open-access publishing of scholarly monographs. It creates open content, on open infrastructure, using open distribution models - to envision a robust programmatic future for open monograph publishing. This work is aligned with the Big Ten Academic Alliance’s development of the BIG Collection's ambition of uniting the collections of the libraries of the Big Ten Academic Alliance.

The Big Ten Academic Alliance continues its advocacy for a sustainable and open ecosystem of publication. Collectively, our institutions’ more than 50,000 faculty are supported by over $11 billion in research funding, and our institutions have similarly invested significantly in our capacity to further our missions to advance knowledge. Together, we produce roughly 15% of the research publications in the United States.
