DARE does not include words that are commonly used throughout the United States, but rather focuses on the regional aspects of our language, documenting words, phrases, and pronunciations that vary from one place to another. It includes audio clips and quotations from the DARE Survey conducted 1965-1970, and an interactive map in addition to the maps that were included in the print version. DARE survey data compiled and edited at the University of Wisconsin-Madison.
