Eugene H. Peterson's Five Smooth Stones for Pastoral Work examines the application of the Megillot to Christian pastoral theology.
The De Rossi Manuscript No. 541, at Parma, was discovered by S. Buber to contain, among other things, midrashim on four of the five "megillot": Canticles, Book of Ruth, Lamentations, and Ecclesiastes; these he published (Berlin, 1894) under the title of "Midrash Zuṭa," to distinguish them from the "Midrash Rabbah."
