This website is an educational project of the Center for Puerto Rican Studies. It contains formerly secret files produced by the Federal Bureau of Investigation (FBI) from the 1930s to the 1990s. The files document FBI surveillance activities and counter-intelligence operations that targeted Puerto Rican organizations and individuals.

The files were released by the FBI in response to the initiative taken by Puerto Rican Congressman José E. Serrano (D-NY) in the spring of 2000. In the summer of that year, the office of Congressman Serrano and The Center for Puerto Rican Studies (Centro) reached an agreement by which a full set of the documents would be forwarded to the Center at Hunter College, CUNY, where they would be catalogued and prepared for public dissemination.

The FBI documents are grouped in three main categories: individuals, programs, and organizations. The section for each category includes historical notes, chronologies, bibliographies, and other tools. In the first stage, the website includes FBI files on Pedro Albizu Campos and Luis Muñoz Marín. The files on programs and organizations will be gradually added.
