Sifrei Aggadah on Esther is a collection of three sets of midrash on the Book of Esther, edited, annotated, and published from manuscripts by 19th-century scholar Solomon Buber. The three sets are entitled: Midrash Abba Gurion, Midrash Panim Acheirim, and Midrash Lekach Tov. The last part is included in a larger work entitled Midrash Lekach Tov, which also includes midrash on other biblical books. Buber had included it in this publication as well, since much of the material in Midrash Lekach Tov on Esther was taken from Midrash Abba Gurion.
