Thank you for your interest in the Harvard Dialect Survey, which concluded in 2003 (Vaux, Bert and Scott Golder. 2003. The Harvard Dialect Survey. Cambridge, MA: Harvard University Linguistics Department). The original questions and maps can be found at http://dialect.redlog.net/ . Dynamic google maps of these and many more dialect questions, as well as a currently running survey with new questions, can be found at Prof. Vaux's current survey site, http://www.tekstlab.uio.no/cambridge_survey/.
