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

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

LIBRARIES and PUBLISHERS

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 Preserve and archive intellectual property Continue to build partnerships with librarians
29
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
