JSTOR has partnered with leading presses on a project to add open access ebooks to JSTOR. Thousands of titles are now available. These open access books are freely available for anyone in the world to use.
An "international, scholar-led open access publishing collective whose mission is to make leading works of contemporary critical thought available worldwide." The OHP network includes several openly accessible book series published by MPublishing at the University of Michigan, as well as a selective list of autonomously-produced open access journals in critical and cultural theory.
