Leona Carpenter describes a JISC development programme tackling the organisational and technical challenges facing Higher and Further Education in the UK.

Physical carriers of digital material deteriorate ; digital data can become corrupted ; the hardware that reads particular carriers wears out and cannot be replaced when it has become obsolete ; file formats become obsolete in the course of software evolution, as backward compatibility is lost over a succession of versions ; older versions of software, even when these are available, may not work on new hardware or operating systems.
Valuable digital assets of institutions are at risk of loss, in the medium-term as well as long-term future.
Challenges to preserving access to these assets are (at least) as much related to organisational process, policy and culture issues as to technical issues. The ways of working that worked in the pre-digital era may not transfer well or easily to a time when a high proportion of the information assets of institutions exist (and indeed are meaningful) only in digital form. Senior managers with finance responsibilities need support in assessing the costs and benefits of digital preservation.
Institutions need processes in place to support decision making about what material requires active intervention and when. These decisions must be based not only on selection and retention policies, sometimes related to legal compliance requirements, but also on judgements of levels of risk to material, and on levels of risk from the loss of particular material or classes of material.
These challenges are common across Further and Higher Education institutions, and institutions can benefit from collaboration and sharing of experience in meeting the challenges. They need support in developing organisational processes and technical systems for digital preservation and access management.
