The goal of the Public Health Image Library (PHIL) is to offer "an organized, universal electronic gateway to the Center for Disease Control's pictures." The site welcomes public health professionals, laboratory scientists, students and the general public to use this material for reference, teaching, presentation, and public health messages. On its homepage, visitors can use the PHIL Quick Search to look for photos, illustrations, or videos. The Featured PHIL Collections contains thematic sections that deal with influenza, natural disasters, environmental health, and bioterrorism. Photographers and those working in health care and education will also want to look over the What's New In PHIL area to get the latest detailed information. Finally, visitors can also use the Contact Us area to have specific queries answered.
