Many of the decrees and resolutions of the Roman Congregations have been published in various collections. Some of the collections are sanctioned by papal authority, the Congregations have vouched for the genuineness of others, while some have received no official recognition. Through the official bulletin of the Holy See, Acta Apostolicae Sedis, the important acts are published bi-monthly. Catholic periodicals in various countries also publish them with more or less completeness: e.g., The American Ecclesiastical Review; The Homiletic and Pastoral Review; The Irish Eeclesiastical Record.
