The University of Kent Templeman Library has taken out a new subscription for Cross-National Times-Series Data Archive.
It includes economic, social and political indicator data from 1815 onwards from over 200 countries including information on military expenditure, electoral data and political systems.
Abigail Heath is currently working on a help guide which will be added to the Library subject webpage.
In the meantime, please feel free to consul this source of information!
