What is CLOCKSS?

A collaboration of the world’s leading academic publishers and research libraries, CLOCKSS provides a sustainable dark archive to ensure the long-term survival of digital scholarly content.

CLOCKSS is a tax-exempt, 501(c)3, not-for-profit charitable organization, developed and governed by libraries and publishers. Unlike other archiving solutions, CLOCKSS answers to its community, not to a parent company. Because CLOCKSS is a 501(c)3 not-for-profit organization, all contributions to CLOCKSS are tax deductible in the United States.

Standing the Test of Time

CLOCKSS (Controlled LOCKSS) employs a unique approach to archiving (Lots of Copies Keep Stuff Safe) that was initiated by Stanford University librarians in 1999. Digital content is stored in the CLOCKSS archive with no user access unless a “trigger” event occurs. The LOCKSS technology regularly checks the validity of the stored data and preserves it for the long term.
