What Is Source of Sources (SOS)?
Source of Sources is a free journalist query platform launched in 2024 as a replacement for the previously popular HARO (Help A Reporter Out) service. The platform distributes daily emails containing journalist requests from major outlets seeking expert sources and commentary.
Journalists from The New York Times, Forbes, The Wall Street Journal, and hundreds of legal industry publications actively use the platform to find expert sources. The platform prioritizes quality responses: founder Peter Shankman explicitly states, "ONLY REPLY IF YOU ACTUALLY HAVE SOMETHING PRODUCTIVE TO ADD." Violating platform norms—such as generic, off-topic, or AI-generated responses—results in permanent removal.
To get started, sign up at sourceofsources.com, select relevant practice area categories that align with your expertise, monitor the daily emails, and respond with specific, original insights when you match the journalist's request.
