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 After cutting those that are outdated, too specialized, or tools of the PR industry, we found a handful worth consulting.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.

SciLine, sponsored by the American Academy for the Advance of Science, is “an independent, freely available service providing timely access to trustworthy, articulate experts for journalists and other communicators producing print, broadcast, or digital stories about science-related issues.” You submit an online request, stating your deadline and the expertise you need.

The Request a Woman Scientist platform sponsored by 500 Women Scientists “connects our extensive multidisciplinary network of vetted women in science with anyone who needs to consult a scientist for a news story, invite a keynote speaker or panelist for a conference or workshop, find a woman scientist to collaborate on a project, or serve as a subject matter expert in any capacity.”

Diverse Sources is a searchable database of underrepresented experts in the areas of science, health and the environment.

Expertise Finder, created by a former journalist and a software engineer, allows reporters to find experts by area of expertise. The search engine generates a list of vetted sources from accredited U.S. and Canadian universities and reputable think tanks. Source pages provide a list of expertise areas, professional bios, and contact information. The service is free and the company reportedly generates revenue by building custom expert directories for universities and colleges.

SheSource, a project of the non-profit Women’s Media Center, is a database of 1,100 vetted female experts on diverse topics around the world, searchable by name, keyword and area of expertise. Source bios and photos are provided and experts can be contacted through a form on the website.

The query is reviewed by HARO editors and sent via email to registered sources and/or their media reps. Interested sources then pitch the querying journalist, who can choose to remain anonymous. According to the company, 55,000 journalists and 800,000 sources are registered with the service. contact emails are provided.

Google Scholar and Microsoft Academic are databases that provide researchers with a comprehensive list of published academic work and its authors by subject search. Results can be prioritized by date and amount of citations to help identify the most relevant academic experts. Some expert pages include bios, publications, affiliations, areas of study, co-authors and links to author websites, as available. Some work is accessible through links or PDF attachments. Google Scholar also has an email alert function, which can notify journalists of new academic publications in their subject area.

Shoeleather, a US database started in 2018 to identify writers from non-media hub cities (NYC, L.A., D.C., SF) who are local, knowledgeable and ready to tell their community stories.

A nice treatment of how to find and nurture sources, and protect them, is Chapter Six in The Investigative Journalism Manual, a 2010 project of the Global Media Programmes of the Konrad Adenauer Stiftung (KAS).
