What type of websites may lack editorial oversight and fact-checking?

Encyclopedia-type websites often allow user-generated content and contributions from the general public without stringent editorial oversight or extensive fact-checking processes. This means that while they can be valuable sources of information, the accuracy and reliability of the content may vary significantly depending on the contributors and their knowledge of the subjects discussed.

Highly-respected publications and standard references, on the other hand, typically have established editorial standards and rigorous fact-checking procedures to ensure that the information they present is credible and accurate. These publications are usually created by expert writers, researchers, or journalists who adhere to professional guidelines. Therefore, while encyclopedia-type websites can provide a wide range of information, they may not always have the same level of reliability due to the potential lack of oversight in the content creation process.
