Digital Preservation through Cooperation: LOCKSS Gail McMillan Digital Library and Archives, University Libraries Virginia Polytechnic Institute and State University VIVA Steering Committee and SCHEV LAC Virginia State University June 10, 2005
Libraries: Collections, not just Links • Libraries should own, as well as manage, their digital collections, including • Content currently leased: VIVA examples • BioOne, Cambridge Uni. Press, Nature Publishing Group, Project Muse • See http://lockss.stanford.edu/about/titles.htm • LOCKSS prevents the publisher from revoking access rights to back content • Open-access web resources, for example • Abbey's Web: Provides links to biographical information, bibliographies, articles, and other resources about the environmental writer, Edward Abbey: http://www.abbeyweb.net/
LOCKSS BasicsLibrary uses inexpensive computer and free software • Programmatically collects content from publisher • Preserves content among LOCKSS servers • Periodically audits content and repairs as needed from other LOCKSS servers • Disseminates content to library’s appropriate users • Host library’s readers see the content from publisher’s URL • Unless it isn’t available from there • It is delivered from the reader’s library’s LOCKSS-preserved content. • It doesn’t look any different.
LOCKSS and EJournals • Library (consortium) negotiates with publishers • Publishers trust LOCKSS • Collections begin with subscriptions, not retrospectively • Libraries have access to their collections in perpetuity • Outside the appropriate user community, access only to audit and repair files • Low cost to administer and run • Less than 1 hour per month • 95% of systems patched in 48hrs • Low storage costs: 2003: $0.70 = one year, one journal, ~0.5GB
LOCKSS software turns a PC into a preservation tool One PC holds >3,000 years of an average electronic journal (2005) 600MHz-128MB RAM-Bootable CD drive-Floppy disk drive
LOCKSS and Publishers • Suggested license language permits libraries to • Collect and preserve currently accessible materials, i.e., subscription-based content • Use materials consistent with original license terms • Provide copies to others for purposes of audit and repair Review of Writing and Photography of Appalachia
LOCKSS is for more than just ejournals • MetaArchive of Southern Digital Culture • ETDs: Electronic Theses and Dissertations • ASERL: Association of SouthEastern Research Libraries • 9/11 web sites -- NYPL • Newspapers -- University of Utah • Government Documents
NDIIPPNational Digital Information Infrastructure and Preservation Program • Created by federal legislation in December 2000 • Support preservation of significant “born-digital” content at risk • Three areas of focus • Network of preservation partners: Clear instructions from legislators that LC should work with others • Architectural framework for preservation • Digital preservation research
MetaArchive NDIIPP Network University of Louisville Va Tech Emory University Ga Tech Florida State University http://www.metaarchive.org Auburn University
Key Features of a Secure MetaArchive • Distributed preservation strategy • Flexible organizational model • Formal content selection process • Capability for migrating archives • Dim archiving strategy • Low cost to deployment • Self-Sustaining incentives • Simple preservation exchange mechanisms with the Library of Congress
MetaArchive Project Goals • Create a conspectus of digital content within the subject domain held by the partner sites • Harvested body of the most critical content to be preserved (3 terabytes, w/ capability to expand) • Develop a model cooperative agreement for ongoing collaboration and sustainability • Distributed preservation network infrastructure based on the LOCKSS software
MetaArchive: Deliverables,more than CLOCKSS • Define the Scope of the Content • What is Southern digital culture? • What is “at risk?” • Developing a Conspectus: Content Selection • What collections will be preserved? • Metadata • Adaptations showing any unique or qualified tags • Rights issues: harvesting for preservation vs. user access
MetaArchive’s CLOCKSS(Collecting Lots of Copies Keeps Stuff Safe) • Diversifying LOCKSS • Software , hardware, collections, communities • Study problems • Dynamic content • Format migration (next grant) • Cooperative agreement model • Not only an effective preservation network for one body of digital content, but enable the creation of many others for this important purpose.
