LIBER Digitisation Conference, Copenhagen
The cost of digitisation and preservation: The LIFE Project
24-26 October 2007

The British Library

Overview
► What is the LIFE Project?
► LIFE1 and LIFE2
► LIFE Models
► Burney Case Study
► Benefits
► Further Information
3
Lifecycle Information for E-literature
Project phases:
► LIFE1 (12 months)
► LIFE2 (18 months)
4
£LIFE starts to answer the question:
What is the long term costof preserving digital material?
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
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 = + *
e.g. 200000 objects of the GIF format for a period of 10 years.
Monitoring formats and software for obsolescence

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.
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
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
