The Marin Institute for the Prevention of Alcohol and Other Drug Problems maintains the Alcohol Industry & Policy Database, which contains bibliographic citations and abstracts for more than 13,000 articles and news stories on the alcohol beverage industry, alcohol policy, and the prevention of alcohol-related problems. The citations in the database span from 1991 to the present and are updated monthly. Users may conduct cross-field queries of the database by keywords, subject headings, company name, and publication date. The search facility includes Word Wheels, which are interactive Java applets that help users to identify indexed terms quickly, thereby "eliminat[ing] trial-and-error searching [and] produc[ing] more accurate searches."
