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

5. A library is a MEMORY organization
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. Locally owned digital collections
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

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 Production
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

28. 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
