In addition to providing counterterrorism education, the CTC also regularly publishes a wide range of analyses and reports in its subject-specialty areas. Some of the most significant and large-scale of these research and analysis products are detailed below.
The Militant Ideology Atlas used
citation analysis to provide the first systematic mapping of the ideologues most influential in the global jihadi movement. Analyzing the most downloaded jihadi literature from one of al-Qa'ida's online libraries and cataloging more than 11,000 citations from these texts, the
Militant Ideology Atlas found that the most influential living jihadi thinkers are not – as is commonly supposed – senior leaders of al-Qa'ida itself, but rather a handful of primarily Saudi and Jordanian clerics; the most widely cited writer is the Palestinian-Jordanian
Abu Muhammad al-Maqdisi. The
Atlas was published in November 2006. Harmony Database Reports are works of analysis and policy recommendation produced by the CTC on the basis of documents declassified for this purpose by the
Defense Department from the latter's Harmony Database, which houses al-Qa'ida-related documents captured throughout the world in the course of the
war on terror. The CTC's first Harmony report,
Harmony and Disharmony: Exploiting al-Qa'ida's Organizational Vulnerabilities, was published in February 2006 and, along with extensive analysis, made primary source documents from the Harmony Database available to the public for the first time. According to the CTC,
Harmony and Disharmony "includes a theoretically informed analysis of potential opportunities to exploit al-Qa'ida's network vulnerabilities, a case study of jihadi operational failure, and specific recommendations for effectively addressing the evolving al-Qa'ida threat." The CTC's second major Harmony report focussed on the
Horn of Africa. Released in May 2007 al-Qa'ida's (Mis)Adventures in the Horn of Africa. provides a detailed picture of al-Qa'ida's efforts to establish itself in East Africa, what its successes and failures were in the region, and how conditions in weak and failed states affect the ability of jihadi groups to function. The report also included a second batch of declassified documents from the Harmony Database, with full English translations, and in-depth profiles of key figures and groups. The entire report can be downloaded. The third Harmony report explores al-Qa'ida's internal conflicts over the course of its history. Released in October 2007, ''Cracks in the Foundation: Leadership Schisms in al-Qa'ida from 1989–2006'' analyzes further declassified Harmony documents in order to tease out the issues that have divided al-Qa'ida's leadership and details the factions that have struggled for control of the organization. Islamic Imagery Project published the first complete catalog of important, recurring images used in violent jihadi propaganda with explanations to enhance the understanding for students, teachers, and policy makers. ==CTC Sentinel==
