CLOCKSS: Controlled LOCKSS

A Trusted Community Archive


Mission

A community-governed partnership of publishers and libraries working to achieve a sustainable, globally distributed Archive and ensure reliable, long-term access to scholarly e-content.

How CLOCKSS Works

CLOCKSS is a not-for-profit, community-governed, partnership of libraries and publishers. Presently seven libraries (six in the U.S. and one in the U.K.) and 11 publishers are participating in the CLOCKSS Pilot Program. Each participating library houses two "CLOCKSS boxes," computers which store and preserve materials to which the libraries do and do not subscribe, in their effort to build a comprehensive archive of web-based scholarly materials. CLOCKSS boxes, using free, open-source LOCKSS software, continuously monitor and self-correct the preserved content to ensure its authenticity over the very long term. When the Board determines a trigger event has occurred, i.e., the digital content is no longer available from the publisher, they will move the content to a hosting platform and the impacted content will be made available for free to the world. When the CLOCKSS Pilot Program concludes in mid-2008, additional publishers and libraries will join the effort to save web-published scholarly literature from disappearing.

CLOCKSS Board Members

One of the strengths of the CLOCKSS Initiative is that the founding organizations, the world's leading publishers and top research libraries, share a long history of survival and a deep understanding of, and experience with, long-term sustainability.
