Fact checking methods include evaluating the reliability of the source of information, searching the Internet or a resource library for reliable sources that confirm information, and consulting with an expert in relevant subject matter. Research libraries like the Library of Congress often assist individuals with resource searches and fact checks.
For some information, fact checks may already be completed and available for public consumption. For political statements, sites like PolitiFact.com and FactCheck.com are commonly used sources for verifying facts.
If the Internet and libraries do not yield clear results in a fact-checking search, research librarians like those at the Library of Congress are often available to search specific resources for information, free of charge.
