About the Intelligence Archives

Sherman Kent, a trailblazer for intelligence analysis, created Studies in Intelligence in 1955. In his first article, Kent argued that intelligence, like any subject, needed formal literature to be taught and developed. Through literature, the study of intelligence could begin to have its own vocabulary, techniques, and even theory. Studies in Intelligence would soon become the primary home for that foundational theory.


The Intelligence Archives is our reference tool for students, scholars, and Central Intelligence Agency practitioners. It combines articles from Studies in Intelligence and papers from the Sherman Kent School of Intelligence. With over 600 articles from the journal and nine Kent Center Occasional Papers, the Intelligence Archives offers a wide range of readings to explore. By recording our experiences, we hope to spread new ideas and build a collective understanding of intelligence as a profession.
