The collection is organized into series for each province according to their number of the Archives General of the Friars of the Order of Preachers [AGOP].

The total collection numbers 37 boxes. The collections for the four U.S. Provinces are the most complete and contain several boxes each while there is more limited selections for 33 other provinces.
