JSTOR is a shared digital library created in 1995 to help university and college libraries to free space on their shelves, save costs, and provide greater levels of access to more content than ever before. More generally, by digitizing content to high standards and supporting its long-term preservation, we also aim to help libraries and publishers of scholarly content transition their collections and publishing activities from print to digital operations. Our aim is to expand access to scholarly content around the world and to preserve it for future generations. We provide access to some or all of the content free-of-charge when we believe we can do so and still meet our long-term obligations. JSTOR currently includes more than 1,700 academic journals, dating back to the first volume ever published, along with thousands of monographs and other materials relevant for education
