Named after ecologist Rachel Carson's landmark book, _Silent Spring_, the Silent Spring Institute (SSI) is a "scientific research organization dedicated to identifying the links between the environment and women's health, especially breast cancer." The SSI website contains descriptions of several research projects including the Cape Cod Breast Cancer and Environment Study, Geographic Information System Exposure Assessment, Groundwater and Drinking Water Initiatives, and Household Exposure Study. SSI also makes a number of downloadable publications available including journal articles and issues of the Institute's own _Silent Spring Review_. The site posts relevant news stories from a variety of sources, and contains a sizeable News Archive as well. In addition, the site offers a great many annotated links, and a glossary with pertinent medical, scientific, and environmental terms.
