Its first result was an edition of the so-called Pesikta de-Rav Kahana, with an elaborate commentary and introduction that exhaustively discuss all questions pertaining to the history of this old Aggadah collection.

Buber's method of dealing with the difficult undertaking was new to scientific literature; and both introduction and commentary received the unstinted praise of the scholarly world.

For a determination of the reading of the text he availed himself of all accessible manuscripts and printed works—and everything was accessible to him, as he spared no expense in obtaining copies of manuscripts and the rarest printed editions; he conscientiously recorded the various readings in footnotes, and he bestowed special care, chiefly in the older midrashim, on the correction and explanation of words in the text borrowed from the Greek and the Latin.

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, Kraków, 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), Kraków, 1895.

Buber's extensive knowledge of Jewish history and literature is also displayed in additions to the works of others and in numerous contributions to Hebrew magazines, such as: Meged Yerachin, Kobak's Jeschurun, Ha-Lebanon, Ha-Maggid, Maggid Mishneh, Ha-'Ibri, Ha-Melitz, Ha Chabatzelet, Ha-Karmel, Joseph Kohn's Otzar Chokmah, Bet Talmud, Ha-Shachar, Ha-Asif, Keneset Yisrael, Zion, Oẓar ha-Sifrut, Ha-Eshkol.

Among the works of his later years the following may be mentioned: Yeri'ot Shelomoh, a supplement to Abraham ben Elijah of Wilna's Rab Po'alim, Warsaw, 1894; a criticism of Yalḳuṭ Makhiri, on Isaiah, ed.

Warsaw, 1893), Kraków, 1895; Ḳiryah Nisgabah, on the rabbis in Zółkiew up to the letter ך, published in Ha-Eshkol, i-iii, 1898–1900; and his contribution to the Steinschneider Festschrift, wherein he propounds a new theory concerning the Petichtot (Introductions) in Midrash Ekah Rabbati.

While there is no denying the positive and profound impact of Salomon Buber on the publication and study of the midrashic literature, there has been some reassessment of the quality of his work in light of more modern methodologies.
