As part of a set of foundational research projects under the theme 'Towards a National Collection: Opening UK Heritage to the World', the Preserving and Sharing Born-digital and Hybrid Objects project aims to contribute to the creation of a unified national heritage collection that includes born-digital cultural heritage. Contemporary culture is increasingly digital. From websites, applications and social media, to digital film, to digital artworks and design tools, creative practitioners in a range of fields are increasingly working with digital or hybrid physical-digital skills. However, this prevalence of digital culture poses a significant challenge to collecting organisations which are responsible for acquiring, preserving and making culture available to the public, now and in the future. In considering how to make our national collections accessible to the world, we must consider born-digital and hybrid material as an increasingly important part of those collections, otherwise we risk failing to preserve the vast majority of our contemporary culture for future generations and entirely omitting this important part of our culture from initiatives to make that culture accessible as widely and as meaningfully as possible. This project seeks to address the challenges of born-digital and hybrid collections by bringing together expertise in a range of different digital cultural types - from archival and library material to film and complex digital design. It will focus on three specific and shared challenges: collections management - the policies, governance, systems and standards needed to support digital collections; digital preservation and conservation - the skills, software and hardware needed to preserve it for the future; and meaningful access and experience - the development of modes of access that do not merely represent digital culture as static, but 'live' as we experience it. It will involve a combination of desk-based research, reviewing and producing reports on current practices, a series of workshops, and the development of two technical pilots. Collectively this research and these outputs will lay the foundations for the future major research initiatives needed to take this forward on a sector-wide scale. The research will be undertaken through an interdisciplinary team of academic and collections-based researchers including representatives from the V&A, BFI, Tate, British Library and Birkbeck, University of London. It will also draw in a number of key industry professionals and will bring national and international participants to a series of workshops that will both involve knowledge sharing and will identify recommendations needed to preserve and make accessible born-digital cultural heritage. By harnessing the collective skills, knowledge and challenges of individuals and institutions involved with different types of born-digital and hybrid cultural heritage, the research project will ensure that born-digital culture remains an integral and research-led part of the national collections of cultural heritage. It will also identify and respond to the need for the development of digital skills and literacy across the cultural sector, so identifying future needs and laying the foundations that are needed in order to truly and inclusively open up the UK's national collections to the world.
