By the way, I have a friend's copy of MT3. I found a small error in the table of contents, which cleared up something I found confusing. Yoel Florsheim's article is on the significance to the text of Rashi's commentary on the Pentateuch of - not Arugot ha-Bosem, but Arugat ha-Bosem. Sorry to nitpick. But the first was written by Tanhum ha-Yerushalmi, and published earlier this year. The second, what he actually meant, was written by R Abraham b Azriel of Bohemia, and was published by Ephraim Elimelech Urbach, in whose honour the article was written.
