Sources

Every source cited by a published claim. Reliability is a prior based on the source type and outlet track record (see methodology); it is one input to each claim's likelihood, not a verdict on the outlet.

Original sources

Who the outlets actually rely on. When several outlets repeat the same original source, it counts as one independent source in the scores.
