Steve Runge notified me a few days ago that Levinsohn’s paper, “Towards a Unified Linguistic Description of οὗτος and ἐκεῖνος,” is now out in print. You can find it in The Linguist as Pedagogue, a volume from Sheffield, edited by Porter and O’Donnell, 2009. I have not seen the volume, but Steve assures me that it contains a number of good papers, including Pennington’s chapter on deponency.
Thanks Steve.
