1. 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

2. 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.htmhttp://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/

3. LOCKSS Basics Library 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.

4. 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

5. 600MHz-128MB RAM-Bootable CD drive-Floppy disk drive One PC holds >3,000 years of an average electronic journal (2005) LOCKSS software turns a PC into a preservation tool

6. 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

7. 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

8. NDIIPP National 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

10. Key Features of a Secure MetaArchive 1.Distributed preservation strategy 2.Flexible organizational model 3.Formal content selection process 4.Capability for migrating archives 5.Dim archiving strategy 6.Low cost to deployment 7.Self-Sustaining incentives 8.Simple preservation exchange mechanisms with the Library of Congress

12. MetaArchive Project Goals 1.Create a conspectus of digital content within the subject domain held by the partner sites 2.Harvested body of the most critical content to be preserved (3 terabytes, w/ capability to expand) 3.Develop a model cooperative agreement for ongoing collaboration and sustainability 4.Distributed preservation network infrastructure based on the LOCKSS software

13. MetaArchiveMetaArchive: 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

14. 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.
