CLOCKSS
Product Highlights
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.
Built on low cost, open source LOCKSS™ technology, the CLOCKSS archive comprises geographically
dispersed nodes located at 15 major research libraries, into which e-content is ingested and preserved.
Content stored in CLOCKSS cannot be accessed until a trigger event is deemed to have occurred and the
CLOCKSS board votes to "light up" the affected titles and restore access to them again. Within the past
year, CLOCKSS experienced three trigger events and responded by releasing the triggered content, making
it free not only to CLOCKSS participants, or to current or former subscribers to that licensed content,
but free to everyone with access to the Internet.

How to Order or Renew
Contact CLOCKSS, and CLOCKSS will send an invoice for the agreed upon annual

new libraries to that schedule.
