The Jerusalem Talmud Index references sources with 5 different page formats based on the various editions of the Yerushalmi.
Perek / Halacha
The Perek/Halacha reference system in the Jerusalem Talmud Index does not reference specific pages, but instead specifies the tractate, chapter, and subchapter where a source can be found. This system may have predated the use of standardized page formats. For example, if someone is looking to find information about activities that are forbidden on Shabbos, they may find a reference that looks like “Shabbos 7:2”, which refers to tractate Shabbos, chapter 7, halacha 2. It is worth noting that while the Bavli refers to each item as a Mishnah, the Yerushalmi calls it a Halacha, and the Mishnah in the Bavli is equivalent to the Halacha in the Yerushalmi
Oz Vehadar / Artscroll
The Artscroll edition of the Jerusalem Talmud uses a new page numbering system, called the Oz Vehadar system, to include commentaries and other enhancements. This means that page references may differ from older editions. The Jerusalem Talmud Index provides the Artscroll page number for each source, but the page images are currently not available. Artscroll also includes the page number in the Vilna edition on the top and in the margin, as well as English translation and notes at the bottom, similar to their edition of the Bavli Talmud.
Vilna Shas
The standard edition of the Talmud Yerushalmi is the 1926 edition, published by Romm and republished multiple times since then. In the Jerusalem Talmud Index, the Vilna Shas is represented as “65b”, which indicates page 65 side 2.
Academy of Hebrew Language
This one volume 1446 page Yerushalmi is based on the 1289 Leiden Manuscript. It was published in 2016. Each reference in the Jerusalem Talmud Index references the page number that the source is found on.
This edition only focuses on the Talmud portion, and therefore doesn’t have any of the Mishnah. When a Mishnah source is referenced in the other columns, a ‘*’ is placed in this column. This source is only a Mishnah and the star points out that this source doesn’t doesn’t exist in this Talmudic edition. For example :
Gittin 8:3 43b 45b * 49a
If the source includes both Mishnah and Talmud, the Jerusalem Talmud Index references the Talmud part of the quote. Although this edition doesn’t quote Mishnah, it does indicate which part of which mishnah the Talmud portion relates to. This Talmud also counts Mishnayos differently, sometimes combining or separating a Mishnah into 2. Therefore the amount of Mishnayos in a perek is different as compared to a different book of Mishnah.
Venice / Bomberg
The Venice / Bomberg edition of 1523 was the first printed Yerushalmi. It is based on the Leiden Manuscript. Each page has 2 columns on each side of the page so that each page number has side a, b, c, and d. Each chapter of Talmud first lists all of the Mishnah, followed by all of the Talmud. The is unlike our present day printings where each Mishnah is followed by the Talmud related to that Mishnah. For example :
46b 46d
This source is in one location in the other columns of the Jerusalem Talmud Index, but in the Bomberg / Venice edition the Mishnah portion is found on 46b and the related Talmud portion is found on 46d.
