 The documents issued by the officials of the Curia and the Congregations of Cardinals contain either resolutions (decisions) for individual cases, or declarations (extensivae or comprehensivae) interpreting laws, or decrees, which are entirely new laws.Some congregations of cardinals have issued official collections of their decisions.Coustant, "Epistolæ Romanorum Pontificum et quæ ad eos scriptæ sunt a S. Clemente I usque ad Innocentium III" (Paris, 1721), goes to only 440; Schönemann, "Pontificum Romanorum a Clemente I usque ad Leonem M. genuinæ ... epistolæ" (Göttingen, 1796); Thiel, "Epistolæ Romanorum Pontificum genuinæ ... a S. Hilaro usque ad Pelagium II" (Brunsberg, 1868).
