Wikimedia UK is the national chapter for the global Wikimedia open knowledge movement, working with the Wikimedia Projects such as Wikipedia to enable people and organisations to contribute to a shared understanding of the world through open knowledge. In this session, Wikimedia UK’s Chief Executive, Lucy Crompton-Reid, will highlight some of the charity’s extensive work in partnership with galleries, libraries, archives and museums to open up access to cultural heritage content, and to increase the representation of marginalised people and subjects on Wikimedia.
