From a press release dated August 13, 2009:
A new collaboration emerges to improve access to scholarship for faculty, students, and librarians. University of California Press and JSTOR today announced a new effort to invest in a shared online platform and outreach services that promise to create a more seamless, rich online work environment for faculty and students, ease the burden on librarians of negotiating separate license agreements with a multitude of publishers and independent titles, and promote a more cost-effective publishing environment.
University of California Press, the not-for-profit publishing arm of the University of California, and JSTOR, the preservation archive and research platform that is part of the not-for-profit ITHAKA, will work in partnership —and encourage others to join them—to make current and historical scholarly content available on a single, integrated platform, to provide a single point of purchase and access for librarians and end users around the world, and to ensure its long-term preservation.
Beginning in 2011, current content from all University of California Press published journals, including those from scholarly societies, will be hosted on a re-designed JSTOR platform. Faculty and students around the world will be able to access all licensed content on JSTOR – current issues, back issues, and a growing set of primary source materials from libraries – easily and seamlessly. JSTOR’s nearly 6,000 library participants worldwide will be able to license the Press’s current journals, either individually or as part of current issue collections, together with JSTOR back issue collections in a single transaction. The journals will also continue to be preserved in Portico, the digital preservation service that is also part of ITHAKA.
