Exploring Republican China in the USC Digital Library: An Experimental Metadata AnalysisThis exploratory study, funded by the FY2021 USC Libraries Research Grant, analyzes the metadata of over 1,500 items in various categories from digital collections related to Republican China (1911-1949) in the USC Digital Library. It uses data visualization, mapping, social network analysis, and other analytic tools to investigate their coverage and connections in terms of geographic locations, timeline, historical figures and events, themes, and possible social networks. The results of this study, particularly the visual mapping and analysis, will help researchers gain a deeper understanding of USC’s Republican China collections.
