OpenMD is a medical reference service that makes high-quality medical information easily accessible to everyone. OpenMD.com searches billions of documents from government agencies, global health organizations, medical journals, and reference sites.

Our approach increases the visibility of medical information from reputable sources, which can often be obscured amid a muddle of commercial results and user-generated content.

Subscription paywalls are commonplace in professional medical reference. We recognize that unexpectedly running into those walls can be a headache. So OpenMD's search prioritizes freely-accessible content whenever available.

OpenMD has also compiled a browsable directory of trusted medical information sources. We believe this expert-reviewed directory to be the most comprehensive index of credible medical sites anywhere on the internet.

Based in New York City, OpenMD is a collaborative effort involving developers and medical professionals from around the world. We hope that this free service is helpful to you in your research.
