Charles Joseph Morrozo, by Rev. D. A. Donovan, O.Cist. (New York and Cincinnati, Fr. Pustet & Co., 1901). With Imprimatur. Available in various formats at Internet Archive and at the HathiTrust Digital Library.

    • [N.B., Although the text attributes the Latin original of the work to the abbot and bishop Mgr. Charles Joseph Morrozo (Carlo Giuseppe Morozzi), HathiTrust Digital Library cites a scholar who states that the author of the work was Giovanni Bona, whom we assume to have been Giovanni Cardinal Bona.]
