Already an important tool for public health investigators, the World Wide Web now offers a new site for one-stop local research in the field: New Haven Health. The Cushing/Whitney Medical Library received a grant from the National Library of Medicine this past winter to create a publicly accessible Web site that will function as a central repository for information about public health in the greater New Haven area. The Web site includes vital and health statistics, current and historical public health documents, community organization listings, aids in the search for related non-digital holdings, and historical images. Browsers will find links to related sites and a listserv for the discussion of public health research. Go to http://www.med.yale.edu/newhavenhealth.
