Unbound Medicine has released Relief Central , a web and mobile resource (a free download, available here for iPhone and iPod touch) that delivers reference information and news to relief workers, first responders, and others in disaster relief situations.

Users can search  The World Factbook from the CIA for detailed information on over 250 countries and territories or review disaster assessment and response guidelines in The Field Operations Guide from the USAID. Relief News gives you up-to-the-minute RSS feeds from trusted government, non-profit, and international resources such as the Centers for Disease Control and Prevention (CDC), Federal Emergency Management Agency (FEMA), Red Cross, ReliefWeb, and more. With Unbound Medicine's selected MEDLINE Journals users can link to the latest abstracts and articles in relevant scientific and medical literature.
