My paper on presupposition accommodation has now appeared:

• von Fintel, Kai. 2008. What is presupposition accommodation, again? Philosophical Perspectives 22(1): 137170. doi:10.1111/j.1520-8583.2008.00144.x.

If you don’t have institutional access to the journal, send me email and I will send you a copy of the article. [More soon on my misguided decision to publish this paper in this journal.]

Update: I recommend a short note by Stalnaker, which just appeared in Linguistics and Philosophy:

Stalnaker, Robert. 2009. A response to Abbott on presupposition and common ground. Linguistics and Philosophy. doi:10.1007/s10988-008-9047-9.
