Kevin Ashley is Director of the UK Digital Curation Center. He was formerly Head of Digital Archives Department, University of London Computer Centre (ULCC). For the past ten years, Kevin's group has worked on the preservation of digital resources on behalf of other organisations. In many cases this has included providing descriptions of those resources and managing access to them. Most of these resources are archival, whether born digital or as digital surrogates, and have involved many types of information (databases, text, video and audio) with different access patterns and cataloguing requirements. Kevin represents ULCC on the board of the Digital Preservation Coalition, was a member of the Advisory Council for Erpanet and part of the RLG-NARA task force seeking to develop an audit and certification mechanism for trusted digital repositories. He speaks frequently on matters related to digital preservation and management of digital content and has contributed to training through the Society of Archivists and the DPC, as well as other organisations.
