While the major theatre collections of universities and libraries in the UK, Europe and the USA have been long established, and companies such as the Royal Shakespeare Company or Ballet Rambert hold their own extensive archives, the past decade has seen increasing attention paid to the need to support smaller theatres in preserving their own records. At the same time, new collaborative practices have emerged in the curation of heritage, often drawing on digital media and technologies: community archives, heritage crowdsourcing, community-university partnerships evidence this participatory turn. This article reflects on an ongoing collaboration with the Theatre Royal Nottingham, UK, and volunteer researchers from the city, to preserve, order and digitally curate the theatre's 150-plus year history. The project builds on the potential of digital technologies -both to enhance participation and engagement and to most effectively capture and represent the interlinked stories and memories mobilized in the making and reception of theatrical performance. In reflecting on the successes and challenges of the project, we develop a model of what we term 'citizen scholarship' in arts and humanities research, which has enabled and supported meaningful and sustained engagement with the theatre's archive and heritage by community volunteers.
