Index of References dealing with Talmudic Literature"The Index, developed by the Saul Lieberman Institute of Talmudic Research at the Jewish Theological Seminary of America, includes the Mishna, Tosefta, Jerusalem Talmud and the Babylonian Talmud. A search for a specific page within the Babylonian Talmud, for example, will yield a list of references to other works in which the Talmudic text is discussed. The Index refers to more than 1000 books from the Geonic period to modern times, covering both modern critical scholarship and traditional works.
A new, exciting feature made possible in the Internet version of the database is direct linking to the text of some of the indexed books, which are available online at Hebrewbooks.org."
