Presentation about the University of Bristol's 'Historical Photographs of China' collection at the GW4 Remediating the Archive digital humanities workshop in Cardiff, November 2016. The 'Historical Photographs of China' project began work in 2006 as part of an AHRC funded project on the 'History of the Chinese Maritime Customs Service' into an initiative that locates, digitises, and publishes online photographs of China held, largely, in private hands outside the country. Although some of the 10,000 photographs now online - a quarter of the total - originate from UK institutional repositories, our materials are principally 'crowdsourced' from families living outside China. This presentation introduces the collection and discusses the technical challenges of growing and sustaining free access to this virtual photographic archive of modern China.
