The Toxicology and Environmental Health Information Program (TEHIP) of the National Library of Medicine (NLM) works to organize and provide access to a wide range of environmental health and toxicology resources. In recent years, the demand for, and availability of, information on health issues related to natural and man-made emergencies and disasters has increased. Recognizing that access to information is essential in disaster preparedness, a new focus of NLM's 2006-2016 Long Range Plan calls for the establishment of a Disaster Information Management Research Center (DIMRC) that will aid in collecting, disseminating, and sharing information related to health and disasters. This paper introduces several of TEHIP's resources for emergency/disaster preparedness and response, such as the Radiation Event Medical Management Web site (REMM) <http://remm.nlm.gov/> and the Wireless Information System for Emergency Responders (WISER) <http://wiser.nlm.nih.gov>. Several of NLM's other disaster preparedness and response resources will also be reviewed.
