Looking for sources? Finding experts in a particular field is a good place to start for many stories. GIJN took a look at various guides to expert sources. After cutting those that are outdated, too specialized, or tools of the PR industry, we found a handful worth consulting. Here are six services with functioning, reliable databases used by journalists searching for expert sources.
