  3. What is a Library?

  4. What Is A Library? • “Libraries have a central role in society as cultural and educational institutions, and as agents for promoting literacy…[they are] essential for better international understanding, and as such they are a fundamental precondition for peace, human rights, literacy, intellectual freedom, and a better environment for all peoples”. IFLA-- 1991

  5. A Library • Serves communities, including nations by • Collecting documents - cultural artifacts (all genres, formats, medium) • Providing intellectual access through interpretation and organization • Preserving artifacts for future community members. • A library is a MEMORY organization

  6. Web’s Impact on Libraries • Libraries now • Lease subscription materials • Access free materials • Libraries unable to • Own collections • Fill memory role

  7. Do libraries have a future? A set of links is not a library Without local collections, libraries will become "digital concierges” • Linking to current digital objects • Mostly common homogenous resources

  8. Librarians must • Assert societal memory role by • Selecting • Building • Preserving • Providing access to • Locally owned digital collections

  9. Digital Publications • Increasingly are the version of record • Often, sole version of record • Change rapidly or disappear, with no warning • Have adjuncts – e.g., hyperlinks, virtual models • Failure to collect digital artifacts will create a growing “dark age” of our times

  10. MOTIVATION http://lockss.stanford.edu

  11. LOCKSS • Open source • Peer to peer • Persistent access preservation system • Web delivered information

  12. Paper Library System • Libraries act for their institution to • Acquire copies of important “stuff” • Keep copies on shelves • Give access to local readers • Libraries cooperate to • Supply copies to other libraries • a reader can easily to find a copy • a “bad guy” has trouble finding and destroying all copies

  13. Paper Library System • Libraries ensure content persists simply by supporting their local communities • A cooperative, affordable, decentralized, preservation system with LOTS OF COPIES

  14. LOCKSS “Library System” • Libraries act for their institution to • Acquire copies of important “stuff” • Keep copies in transparent web caches • Give access to local readers • Libraries cooperate to • Detect and repair damage • a reader can easily find a copy • a “bad guy” has trouble finding and destroying all copies

  15. LOCKSS “Library System” • Libraries ensure content persists simply by supporting their local communities • A cooperative, affordable, decentralized, preservation system with LOTS OF COPIES

  16. LOCKSS • Support: Mellon, NSF • Software: www.sourceforge.net • Teams: Research and Production

  17. Teams • Research • Stanford, Harvard Computer Science, Hewlett Packard, Intel • Award winning research • 2004: ACM Grand Finals 2nd place Best Paper SOSP • Investigating LOCKSS communication • Scaling, attack resistance • Production • Deploys research findings, builds and maintains system, provides user support

  18. Partners 70+ Publishers 100+ Libraries

  19. LIBRARIES and PUBLISHERS

  20. LOCKSS software turns a PC into a persistent web cache into a preservation tool 1 PC holds ~2,500 e-j years 600MHz-128MB RAM-Bootable CD drive-Floppy disk drive

  21. LOCKSS Caches • Crawls and collects HTTP content • All formats (PDF, HTML, JPEG, TIF, Audio, Video) • Preserves content integrity • Independent collection • Cooperate to audit and repair damage • Provides access • Via web browser • Content is never “dark”

  22. LOCKSS Caches

  23. Approximate Data Flows LOCKSS machines

  24. Approximate Data Flows LOCKSS machines (proxy servers) Prevent the publisher from revoking access rights to back content

  25. Publisher Gives Permission

  26. Bringing Up A LOCKSS Cache • Get a static IP address • Get a PC (floppy, CD, and lots of storage) • Download CD image from LOCKSS web site • Burn CD image on CD-R • Boot PC from CD and insert blank floppy • Follow on-screen instructions and answer configuration questions • Wait for network and preservation systems to start up • Configure titles for collection & preservation

  27. LOCKSS Allows Publishers to • easily and affordably • With minimal risk to business model • With minimal risk to publishing platform • Fulfill requirement to guarantee “perpetual access” to subscribed materials • Preserve and archive intellectual property • Continue to build partnerships with librarians

  28. LOCKSS allows libraries to • easily and affordably • Build e- collections • Preserve important materials • Deliver content to current and future readers when publisher is not available • Own rather than lease or access • Retain traditional custodial role
