Preserving Scholarship for Future Generations

A global leader in digital preservation services

We are CLOCKSS. A community-led collaboration of academic publishers
and research libraries around the world, working together to provide
a sustainable online archive. Together we ensure the long-term
survival of our shared intellectual heritage.

At CLOCKSS, through the services we provide to libraries and
publishers and built over the award winning LOCKSS software, we
instill confidence in authors, scholars, policy makers, libraries,
and publishers that scholarship is safely and securely preserved for
future generations.

As global leaders in digital preservation, we ensure that all books,
journals, and digital collections entrusted to CLOCKSS are protected
and preserved indefinitely.

Why CLOCKSS?

Sustainable Long-Term Digital Archive

CLOCKSS provides a sustainable online archive to ensure the long-term
survival of digital scholarship. Digital content is preserved in the
CLOCKSS archive with no user access unless a "trigger" event occurs.

Worldwide Collaboration

CLOCKSS preserves content in 12 archive nodes located at leading
research libraries around the world, preserving the authoritative
versions of journal articles and book titles plus associated data,
images, software, videos, and web archives.

Quality Research Content

The content preserved by CLOCKSS is selected by research libraries
and is quality assured by reputable academic publishers.

Innovative Technology and Services

CLOCKSS uses award-winning LOCKSS technology to preserve content.
CLOCKSS preserves scholarly content in original digital formats and
migrates this content to new formats to ensure it remains usable.
CLOCKSS safeguards scholarship against the long-term, well-documented
causes of digital loss: human error, computer attacks, economic and
organizational failure. In an ever-changing world we remain future
oriented and proactive and are proven leaders in long-term digital
preservation.

Permanent Open Access

CLOCKSS assigns Creative Commons Open Access licenses to all
triggered publications to ensure they are open and available to
everyone.
