Complementary to research libraries building local collections with LOCKSS and geographical arrangements for legal deposit. CLOCKSS is an important strategic component in a multilayer, resilient, local and international preservation plan.
11. Context Preserved
Content ingested via presentation files preserve branding and publisher's look and feel.
10. Technically Robust
Award-winning open source software with demonstrated capacity to recover from natural disasters, human folly, and digital decay through continuous and systematic audit and repair.
9. Cost Effective
Support preservation and keep maximum funds available for publishers to publish and librarians to buy new materials. Fees are low and for a limited period while we build the CLOCKSS Endowment which we expect to underwrite costs after five years.
8. Award Winning
Winner of the ALA's Association for Library Collections & Technical Services (ALCTS) 2007 Outstanding Collaboration Award and the 2004 ACM Award for Underlying LOCKSS Technology.
7. Long-term Sustainability
Building an endowment to reduce dependence on revenue income to ensure preservation and access even in tough economic times.
6. Global Participation
The network of globally distributed nodes in the CLOCKSS Archive spans geographic, political, and legal boundaries.
5. Comprehensive Coverage
Underlying LOCKSS technology preserves a diverse range of materials. Publishers co-govern, trust CLOCKSS, and are eager to have their content preserved via the CLOCKSS Archive.
4. Access For All
Upon release of "orphaned" or triggered content, CLOCKSS makes access to the content free to the public, without need for any prior subscription, fee, or registration.
3. Library Custody
CLOCKSS Archive node libraries are custodians of the content. Library stewardship and responsible action by publishers leverages the strengths and existing infrastructure of both entities.
2. Community Governed
Publishers and librarians work as equals to pursue a common goal and effect change in their industry. As a self-governed Community Archive, CLOCKSS gives libraries and publishers a voice to influence industry policy decisions that affect them directly.
