Buber distinguished himself in other departments of literature. His first work was a biography of the grammarian Elias Levita, published at Leipzig in 1856. After this he edited the following: "De Lates' Gelehrtengeschichte Sha'are Zion," Jarosław, 1885; Zedekiah ben Abraham's liturgic work, "Shibbole ha-Leket," Wilna, 1886; "Pesher Dabar," Saadia Gaon's treatise on the "Hapax Legomena" of the Bible, Przemyśl, 1888; Samuel ben Jacob Jam'a's "Agur," introduction and additions to the "Arukh", Breslau, 1888 (in "Grätz Jubelschrift"); Samuel ben Nissim's commentary on the "Book of Job", "Ma'yan Gannim," Berlin, 1889; "Biurim": Jedaiah Penini's explanations of "Midrash Tehillim", Cracow, 1891, and a commentary on "Lamentations" by Joseph Caro, Breslau, 1901 (in the "Kaufmann Gedenkbuch"); "Anshe Shem," biographies and epitaphs of the rabbis and heads of academies who lived and worked at Lemberg, covering a period of nearly four hundred years (1500-1890), Cracow, 1895.
