A leading digital archive for academic publishers and research libraries

At CLOCKSS our ethos is simple: we exist to preserve the hard work and knowledge of scholars.

We achieve this through our global community of libraries and publishers, with whom we work in collaboration with, to mitigate potential issues and risks, to seek future-proofing solutions, and to deliver a leading digital archive for the scholarly community.

CLOCKSS is governed by a Board of Directors with an equal number of librarians and publishers making decisions together about policies, procedures, priorities, and when to trigger content. This inclusive approach ensures everyone’s interests are upheld and that the preservation of content is at the heart of everything we do.
