What are secondary sources? Secondary sources are works of synthesis and interpretation based upon primary sources and the work of other authors. They may take a variety of forms.

Visualising China is a JISC-funded project to allow users to explore and enhance more than 8000 digitised images of photographs of China taken between 1850 and 1950. It allows access to many previously unseen albums, envelopes and private collections and also major collections such as Historical Photographs of China, the Sir Robert Hart Collection and Joseph Needham's Photographs of Wartime China. These have many sub-collections and albums. We hope you will contribute by using your knowledge to comment on or annotate these images.
