Some links to reports, databases, and datasets.
The Conflict Records Research Center (CRRC) and the John Hopkins Center for Advanced Governmental Studies have released an e-book containing edited presentations from the September 2011 conference, “Ten Years Later: Insights on al-Qaeda’s Past and Future through Captured Records”. Of particular interest is the paper by Cynthia Storer, “Working with al-Qaeda documents: An Analysts View Before 9/11”. The CRRC also have an index of a number of the al-Qaeda and Associated Movements (AQAM) documents held at the CRCC.
The Robert S. Strauss Center for International Security and Law has a database and analysis available for Africa. According to the website, “The Social Conflict in Africa Database (SCAD) is a resource for conducting research and analysis on various forms of social and political unrest in Africa.” A presentation of some of the initial analysis is here and here. The dataset looks promising although a look at some of the Algeria-related data suggests some problems as the June 2005 attack by the GSPC against the Mauritanian military appears twice.
John Jay & ARTIS Transnational Terrorism Database (JJATT) has a selection of datasets, “on radical Islamists, their associates, and case studies of their collective behavior.” It appears to be based in part on data collected by Scott Atran.
