LPC Blog

The Library Publishing Coalition Blog is used to share news and updates about the LPC and the Library Publishing Forum, to draw attention to items of interest to the community, and to publish informal commentaries by LPC members and friends.

The Library Publishing Coalition is delighted to welcome CLOCKSS as a new strategic affiliate! A statement from CLOCKSS:

We are looking forward to working with LPC and the LPC community!

A collaboration of the world’s leading academic publishers and research libraries, CLOCKSS provides a sustainable dark archive to ensure the long-term survival of Web-based scholarly content.

CLOCKSS (Controlled LOCKSS) employs a unique approach to archiving (Lots of Copies Keep Stuff Safe) that was initiated by Stanford University librarians in 1999. Digital content is stored in the CLOCKSS archive with no user access unless a “trigger” event occurs. The LOCKSS technology regularly checks the validity of the stored data and preserves it for the long term. CLOCKSS operates 12 archive nodes at leading academic institutions worldwide, preserving the authoritative versions of 43 million journal articles, over 25,000 serial and 240,000 book titles, and a growing collection of supplementary materials and metadata information. As of March 2020, 64 titles have been triggered and made available from our archive via open access. CLOCKSS participants include 300 libraries and 400 publishers.

This secure, robust, and decentralized infrastructure can withstand threats from technological, economic, environmental, and political failures. A destructive event in one location won’t jeopardize the survival of preserved digital content because the 11 other locations serve as mirror sites to back-up and repair the disrupted location’s archive.

CLOCKSS is governed by and for its stakeholders. Our operations are 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. As an independent, tax-exempt 501(c)(3) not-for-profit charitable organization, CLOCKSS is committed to keeping its fees affordable, for libraries and publishers of all sizes and budgets to participate in CLOCKSS. Low operating costs make it possible to keep this commitment. As a long-term preservation organization, CLOCKSS believes that a robust Succession Plan is required. In the unlikely event of the demise of CLOCKSS, four of our twelve library nodes have committed to continuing the preservation of the content in the Archive.

As the only dark archive that assigns a Creative Commons license to all triggered digital content, CLOCKSS benefits the greater global scholarly community by enabling permanent Open Access to abandoned and orphaned publications. As a result, recovered content becomes perpetually available to anyone with Internet access.

Strategic affiliates are peer membership associations who have a focal area in scholarly communications and substantial engagement with libraries, publishers, or both. See our list of strategic affiliates or learn more about the program.
