The University of Pennsylvania Working Papers in Linguistics (PWPL) is an occasional series published by the Penn Linguistics Club. The series has included volumes of previously unpublished work, or work in progress, by linguists with an ongoing affiliation with the Department, as well as volumes of papers from NWAV and the Penn Linguistics Colloquium. This volume contains selected papers from the 41st NWAV Conference, held from October 25-28, 2012 at Indiana University in Bloomington, IN. Thanks go to Christopher Ahern, Hezekiah Akiva Bacovcin, Sunghye Cho, Eric Doty, Aaron Ecay, Sabriya Fisher, Amy Goodwin Davies, Soohyun Kwon, Marielle Lerner, Hilary Prichard, Kobey Shwayder, Einar Freyr Sigurðsson, and Elizabeth Sneller, for help in editing, uploading, and general support. Since Vol. 14.2, PWPL has been an internet-only publication. Since Vol. 13.2, PWPL has been published both in print and online gratis via ScholarlyCommons@Penn. Due to the large number of hits these online papers have received, and the time and expense of managing a back catalog of PWPL volumes, the editorial committee decided in 2008 to cease print publication in favor of wider-scale free online dissemination. As of September 2013, the entire back catalog has been digitized and made available on ScholarlyCommons@Penn. Please continue citing PWPL papers or issues as you would a print journal article, though you may also provide the URL of the manuscript. An example is below: Mielke, Jeff. 2013.
