לשאלת קדמותן של "תוספות ישנים" למסכת ראש השנה

A number of substantive sources and linguistic evidence reviewed in this study indicate that the Tosafot Yeshanim to Tractate Rosh Hashanah are, as their name implies, part of the ancient addition of Tosafot, and that Tosafot Yeshanim precede the common Tosafot Shantz. The article clearly indicates that the Tosafot Yeshanim were written by a student of R. Isaac b. Samuel de Dampierre (Ri HaZaken) in the 12th century, and are not a late edition of Tosafot from the second half of the 13th century. Tosafot Yeshanim are probably the early edition of Tosafot Shantz. There is also a possibility that the Tosafot Yeshanim collection was edited and processed, and therefore includes later additions to the text.
