£LIFE starts to answer the question:
What is the long term costof preserving digital material?
![Page 5: LIBER Digitisation Conference, Copenhagen The cost of digitisation and preservation: The LIFE Project 24-26 October 2007 Richard Davies LIFE 2 Project.](https://reader030.fdocuments.net/reader030/viewer/2022032801/56649e265503460f94b15cd3/html5/thumbnails/5.jpg)

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

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

Preservation action
Preservation cost of n objects of a particular format for the period 0 to t.
Preservation = + *
e.g. 200000 objects of the GIF format for a period of 10 years.
Monitoring formats and software for obsolescence
Preservation planning

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?
![Page 20: LIBER Digitisation Conference, Copenhagen The cost of digitisation and preservation: The LIFE Project 24-26 October 2007 Richard Davies LIFE 2 Project.](https://reader030.fdocuments.net/reader030/viewer/2022032801/56649e265503460f94b15cd3/html5/thumbnails/20.jpg)

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
