What's in CLOCKSS

Preserving scholarship for future generations

Transparency is an essential part of digital preservation. To ensure that information about our archival holdings is widely available, CLOCKSS provides full information on this page, and we also participate in the Keepers Registry run by the ISSN International Centre. The Keepers Registry aggregates preservation information provided by participating preservation agencies to make it easier to discover what is preserved where.

New reports are made available to the Keepers Registry on the first day of the month at around 12:00 UTC.
