Published books and articles that you find via the Pace Libraries have already been vetted for accuracy, authority and purpose. This doesn't mean that there is no disagreement in the world; it just means that publishers, editors, and the authors' peers have found the article or book to be credible, authoritative, accurate and educational: the publication presents new knowledge or perspective.
Internet results have not, in any general way, been vetted for accuracy, authority, and purpose. I lot of material on the Internet has a commercial (ad driven) purpose and is designed to attract clicks. Using Internet sites as sources of information means taking time to confirm that the information, argument, or data is legitimate and can be trusted (or has at least been published by a reputable publisher or organization). You might immediately recognize a source like The New Yorker magazine or The Los Angeles Times newspaper. You might recognize a government office like NASA (The National Aeronautics and Space Administration). Other sources won't be as well known, and those are the ones you have to investigate.
Social media is the very worst place to look for information you can trust. People often repost articles without even reading them, and bad actors post fake news. See this library guide Fake News: Misinformation, Disinformation, and Malinformation for more about the subject.
