As a best practice, all primary sources should be verified before used. This helps to ensure that the information is accurate and reliable. There are a few different ways to verify sources, and the best method will vary depending on the type of source and the amount of information available.
One way to verify a source is to check for other sources that corroborate the information. This can be done by conducting a search for key terms related to the information in question. If multiple sources are reporting the same thing, it is likely that the information is accurate.
Another way to verify a source is to contact the source directly. This is often possible for sources such as government agencies, businesses, and organizations. If the source is a person, you may be able to verify their identity and credentials by speaking with them directly or by checking for other public records.
