Bavli and Yerushalmi
The process of "Gemara" proceeded in what were then the two major centers of Jewish scholarship, the Land of Israel and Babylonia. Correspondingly, two bodies of analysis developed, and two works of Talmud were created. The older compilation is called the Jerusalem Talmud or the Talmud Yerushalmi. It was compiled in the 4th century in Israel. The Babylonian Talmud was compiled about the year 500 CE, although it continued to be edited later. The word "Talmud", when used without qualification, usually refers to the Babylonian Talmud.
While the editors of Jerusalem Talmud and Babylonian Talmud each mention the other community, most scholars believe these documents were written independently; Louis Jacobs writes, "If the editors of either had had access to an actual text of the other, it is inconceivable that they would not have mentioned this. Here the argument from silence is very convincing."
