Periodica de re canonica, more frequently called Periodica, is the journal of the Faculty of Canon Law of the Pontifical Gregorian University.

Beyond studies and canonical research, the journal publishes comments regarding rotal sentences and decrees of the Apostolic Signatura. The conferences of "Colloqui" of alumni of the faculty are also produced.

The fourth issue of each year reports information on the Faculty's doctoral dissertations: topics presented by students, dissertations defended and dissertations published.

The journal is open to contributions from professors of the Faculty, rotal judges, curial officials, those who work in tribunals, and other canonists. Sometimes the results of more interesting doctoral dissertations from within the Faculty are published. The task of the journal is to consider new developments in canonical doctrine, Church legislation and administration, and to be open to new horizons in reflection on ecclesial reality. Typically, the journal Periodica de re canonica does not publish reviews and writings previously published elsewhere.

Every article will be subject to a double evaluation, which will remain anonymous, by two censors, external e independent of the institution. 

Each volume (annual) of Periodica is published in four issues of about 700 pages in total. Articles can be written in Latin, Italian, French, English, Spanish and German.
