Audiovisual Materials

  • Still Images: Embedded Collections (image searching in journal databases, eg. AP Images, ARTstor, Cinema Image Gallert frin Wilson web), portals (Collections of Image Sites from Trustworthy Sources -- The Interntational and Area Studies Librarians at Duke maintain excellent image portals in the research guides for their respective areas); and commercial collections (ORBIS, carge for use, but browsing is free)
  • Moving Images (Video/Films)
  • Sound-recordings – such as oral histories, political speeches = eg. Search by format ("Audio") for keyword (eg. "human rights")

Numerical & Geospatial Data

  • Maps and geographic information systems (GIS)
  • Non-spatial data sets – indices do not take into account any spatial relationships of the geographical entities (i.e., distances apart, clustering within, spatial concentrations, etc.).
  • Using Statistics (Purdue): Numbers don't speak for themselves. Here's advice on how to use statistics effectively. Be sure to check out Duke University Libraries' International Statistics collection.
