As of December 2009, 138 books of the Institute proceedings and studies have been published. Some of the proceedings of the Institute's activities are contained in the Revue Internationale de Droit Pénal and Nouvelles études Pénales, others are published in-house by the Institute in the series Quaderni.

The Institute also has publishing agreements with two major Italian publishing companies, Cedam (Padova) and Jovene (Naples), for Italian language publications, such as the series on Legal Psychology (currently 18 volumes). In addition, the Superior Council of Judges (Consiglio Superiore della Magistratura) has published five books of conference proceedings it co-sponsored with the Institute. Major book publishers in the U.S., France, Italy, Lebanon and the Netherlands have also published some of the Institute's proceedings.

Almost all the volumes produced by the Institute are the result of meetings it organized, and include original contributions from the world's leading experts in criminal law and human rights issues.

The scientific input given by the Institute to the debate surrounding a permanent international tribunal formed a basis for the elaboration of the Statute of the International Criminal Court, and is one of its most outstanding contributions to the study of international and comparative criminal law.

Through its roster of experts and that of the AIDP, the intellectual outgrowth of the Institute has reached thousands of professors, policy-makers, criminal justice officers, and scholars throughout the world.
