Why should a law library concern itself with a slang dictionary? It's true that the original survey questionnaire, which circulated within 1,000 representative American communities between 1965-1970, doesn't cover much law-related ground (unless you count question P35's descriptions of "illegal methods for shooting deer" – generally at night, and known as "fire-lighting" in South Carolina, "jack-light" in the Northeast, and "headlighting" around Texas, according to the regional response map). But dictionaries of all kinds are an important tool for legal researchers, and U.S. Supreme Court Justice Clarence Thomas even cited to DARE last year while dissenting from the majority in Smith v. Cain. Surprisingly, the Smith dissent looks to be this dictionary's first appearance in a published federal court opinion, although it has also been cited in trial motions and appellate briefs.
Other dictionaries, of course, are regularly cited in court opinions: DARE's more highbrow cousin The Oxford English Dictionary has been name-checked by courts literally thousands of times, and can be found not far from DARE in the Goodson Law Library, at the call number Ref PE1625 .O87 1989 or in an online version available to the University. The full text of DARE is not yet available online, although the website currently offers 100 entries as well as reel-to-reel audio samples of the 1960s survey respondents.
Whether you need to know the definition of a legal term of art or a confusing piece of slang, be sure to Ask a Librarian for some good starting places.
