CLOCKSS (Controlled LOCKSS) is a not for profit joint venture between the world’s leading scholarly publishers and research libraries whose mission is to build a sustainable, geographically distributed dark archive with which to ensure the long-term survival of Web-based scholarly publications for the benefit of the greater global research community.
CLOCKSS is for the entire world’s benefit. Content no longer available from any publisher (“triggered content”) is available for free. CLOCKSS uniquely assigns this abandoned and orphaned content with a creative commons license to ensure it remains available, forever.
