HARO, or “Help a Reporter Out,” can be a reporter’s best friend. To use the service, simply register and submit a free source request, including a synopsis of what you want to learn, any required qualifications, and your reporting deadline. HARO will send your message to its network and potential sources will find their way to your inbox. The site boasts over 475,000 sources in its network.
We have used this service to find experts in fields beyond my normal network as well as to find “regular people” to interview. Many HARO subscribers work full-time for an organisation, but still fit other subject criteria you’re looking for (like Uber drivers or baseball coaches).
