A white paper released by Cornell University Press reviewing their NEH Humanities Open Book Program notes exceptionally high levels of discovery and usage on JSTOR. The paper states that the 20 titles Cornell University Press is making available on JSTOR saw a total of more than 15,000 chapter downloads in less than six months—more than in all the other platforms in which they make the ebooks available combined.

JSTOR currently partners with 14 leading publishers to make more than 550 open access titles available at no cost to libraries or users.
