The cost of digitisation and preservation: The LIFE Project Richard DaviesLIFE2 Project Manager,The British Library LIBER Digitisation Conference, Copenhagen 24-26 October 2007
Overview • What is the LIFE Project? • LIFE1 and LIFE2 • LIFE Models • Burney Case Study • Benefits • Further Information
Lifecycle Information for E-literature Project phases: • LIFE1 (12 months) • LIFE2 (18 months)
LIFE starts to answer the question: • £ • What is the long term costof preserving digital material?
Why use lifecycle costing? • Enables evaluation of all the financial commitments for an item in a collection • Important for digital collections, where many costs are largely unknown
Aims • Better understanding of the digital lifecycle • Plan and prepare for digital preservation activities • Evaluate and improve efforts • Compare analogue and digital
LIFE1 project • Literature Review • Economic Lifecycle Model • Generic Preservation Model • Case Studies • International Conference
LIFE1 Case Studies e-Journals Web Archiving Voluntary Deposit
LIFE1 • LIFE2
Aim of LIFE2 To evaluate, refine and further develop the techniques developed in phase one of LIFE
LIFE2 deliverables • Economic Evaluation of LIFE1 • Revision of the LIFE Model • Version 1.1 (October 2007) • Version 2 (Summer 2008) • Updated Preservation Model (Summer 2008) • Final report • End of project conference

Preservation Actions: • Preservation Tool Cost • Preservation Metadata • Performing preservation action • Quality Assurance Generic LIFE Preservation Model • The GPM predicted large cost and much activity - the challenge is reducing both.

The Burney Collection • Purchased by the British Library in 1818 for £13,500 • 1,100 volumes of the earliest known newspapers • 1,000,000 pages from 17th, 18th and 19th Centuries. • Re-scanning or re-microfilming is not possible. • Microfilmed in the 1970s • Digitisation started in 1995-96 and ran until 2004.
Questions that arise from Burney • Comparing digital and analogue lifecycles • What is the lifecycle cost to an institution of producing digitised surrogates? • What are the key preservation issues common across digitisation projects of differing scales?
Benefits of LIFE • Assess the financial commitment for acquiring or creating new digital materials • More effective planning for preservation activities • Comparison of digital lifecycles across collections • Evaluation and optimisation of existing digital lifecycles • Predictive future cost of digital preservation
