The greatest service which Eisengrein rendered the University of Ingolstadt was his organization of its library. It was owing to his efforts that the valuable private libraries of Bishop Johann Eglof von Knöringen, of Augsburg, Thaddeus Eck, chancellor of Duke Albert, and Rudolph Clenek, professor of theology at Ingolstadt, were added to the university library. Works Eisengrein's activities were not confined to the university. By numerous controversial sermons, some of which are masterpieces of oratory, he contributed to the suppression of Lutheranism in Bavaria. Many of his sermons were published separately and collectively in German and Latin during his lifetime. Some have been edited by Johann Nepomuk Brischar in "Die kathol. Kanzelredner Deutschlands" (Schaffhausen, 1867–70), I, 434-545. He is also the author of a frequently reprinted history of the shrine of the Blessed Virgin at Altötting (Ingolstadt, 1571) and a few other works of minor importance.
