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 The series has included volumes of previously unpublished work, or work in progress, by linguists with an ongoing affiliation with the Department, as well as volumes of papers from NWAV and the Penn Linguistics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 NWAV 39, held from November 4-6, 2010 in San Antonio, TX at the University of Texas at San Antonio. Alphabetic thanks go to Claire Crawford, Aaron Ecay, Lauren Friedman, Kyle Gorman, Soohyun Kwon, Marielle Lerner, Laurel MacKenzie, and Hilary Prichard for help in editing. 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. 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: Acton, Eric K. 2011.

Tamminga, 1-9. http://repository.upenn.edu/pwpl/vol17/iss2/2 Ultimately, the entire back catalog will be digitized and made available on ScholarlyCommons@Penn. Publication in the University of Pennsylvania Working Papers in Linguistics (PWPL) does not preclude submission of papers elsewhere; copyright is retained by the author(s) of individual papers.
