Primary sources are original documents or objects that provide first-hand information, such as historical documents, experimental results, statistical data, creative works, or eyewitness accounts. Secondary sources discuss or interpret primary sources and include articles, books, or scholarly works. When evaluating the reliability of a source, consider factors like whether the information is current, the reputation and type of publication, the author's qualifications and potential for bias, and whether the author directly witnessed the information or gathered it from other sources.
