1 LIBER Digitisation Conference, Copenhagen The cost of digitisation and preservation: The LIFE Project 24-26 October 2007 Richard Davies LIFE 2 Project Manager, The British Library

2 2 Overview ► What is the LIFE Project? ► LIFE 1 and LIFE 2 ► LIFE Models ► Burney Case Study ► Benefits ► Further Information

3 3 Lifecycle Information for E-literature Project phases: ► LIFE 1 (12 months) ► LIFE 2 (18 months)

4 4 £ LIFE starts to answer the question: What is the long term cost of preserving digital material?

5 5 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

6 6 Aims ► Better understanding of the digital lifecycle ► Plan and prepare for digital preservation activities ► Evaluate and improve efforts ► Compare analogue and digital

10 10 Aim of LIFE 2 To evaluate, refine and further develop the techniques developed in phase one of LIFE

11 11 LIFE 2 deliverables ► Economic Evaluation of LIFE 1 ► 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

14 14 Generic LIFE Preservation Model The GPM predicted large cost and much activity - the challenge is reducing both. Preservation Actions: 1.Preservation Tool Cost 2.Preservation Metadata 3.Performing preservation action 4.Quality Assurance

18 18 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 17 th, 18 th and 19 th Centuries. ► Re-scanning or re-microfilming is not possible. ► Microfilmed in the 1970s ► Digitisation started in 1995-96 and ran until 2004.

19 19 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?

20 20 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
