The KB e-Depotlong-term preservation of scientific publications in practice
Marcel Ras, National library of The Netherlands
Libraries: traditional or digital
What is the problem with digital?
• Digital information needs an intermediary to be interpreted– Hardware, operating system, software
• Physical carriers can be damaged. Digital carriers too and can become obsolete
• There is an awful lot of digital information– annual growth of 500 million TB– 2008: 490 billion GB of information produced on the internet
(30 billion iPods)
• We rely on digital information• Digital information only (no paper equivalent)
The KB
• KB is national library of The Netherlands• Task of a national library is to collect, describe and preserve
national imprint• Paper, but also digital• National deposit since 1974 (but no deposit legislation)
• 49 km books (2,5 million)– annual growth: 38.000
• 18 km journals – annual growth : 11.000
• over 1 km microfilm• 13 million digital scientific articles
– annual growth: 3 million
The KB e-Depot (2)
• Digital version of traditional depot• Operational since 2003• No legal deposit legislation• Based on agreements with publishers• International focus • International scope of scientific output• Safe Places Network
History of the KB e-Depot
1994: e-publications part of deposit: need for an infrastructure
1995: Experiments with Elsevier, Dutch Publishers Association
2002: Landmark archiving agreement with Elsevier
2003: e-Depot system operational
2006: start project with Academic repositories
2007: Archiving agreements with major 19 STM publishers
2007: Start development ingest procedures for other materials
2008: co-operation with Open Access communities (DARe / DOAJ)
What do we preserve?
e-journals international (22 million - 30 TB)
digitized masters (21 million - 275 TB)
websites (100.000 - 120 TB)
IR's (300.000 - 30 TB)
e-books international (1 million - 30 TB)
e-books national (400.000 - 15 TB)
e-journals national (600.000 - 10 TB)
Why should we bother?
• Accessibility of scientific information and knowledge is in danger• Next generations do not have access to the information of our era
(digital dark ages)• E-only and e–communication only• Digital information is extremely fragile
– Thread for cultural heritage– Thread for scientific research– Financial consequences
Should we bother?
• BBC Domesday project• 1086:William the conqueror • 1986: information on British society stored
on state-of-the-art laser disks• After 20 year carrier and hardware were
useless
What can we do?
Digital Preservation
• Long-term and safe storage• registration• Tools for permanent access
Preservation metadata

+ permanent access
Time machine
storage
storage
Digital archive
Registration
Time machine
Preservation research
• Research on file formats and tools– Characterization (Jhove, Droid)– validation
• Preservation strategies– Migration– Emulation
• Preservation metadata– PREMIS
• Preservation planning• storage• R&D results directly implemented into e-Depot infrastructure• Quality improvement is continuous process• International collaboration
What does it cost?
• Initial costs for development (2000 – 2003)• Annual costs, of which
– Operational Staffing: 30 %– Project staffing & development: 25 %– Maintenance + hard- software licenses: 25 %– Storage: 20 %
• But how to calculate– Preservation management– Preservation actions
• Annual costs about 4 million euro

New challenges
• New collections to be preserved– Websites, digitized materials, institutional repositories
• New content types– e-books, image files, AV, multimedia, complex objects
• Hybrid collections– Websites– Publications & research data– Analog & digital combined– “liquid publications”– Compound objects
• Growing storage capacity– From 11 TB to 500 TB
Conclusions
• Preservation is not just storage and technique• It demands for long-term organizational commitment• It requires continuous research• It requires substantial investments in infrastructure and
up-to-date expertise and skills• It brings organizational changes
– Process innovation: from traditional library to digital library– e-Depot brought new set of skills to the “traditional” library– Organizational change
• It asks for constant rethinking: next generation LTP solution
