Credibility is defined as the quality or power of inspiring belief. Credible sources, therefore, must be reliable sources that provide information that one can believe to be true. It is important to use credible sources in an academic research paper because your audience will expect you to have backed up your assertions with credible evidence.
When constructing your research paper, it is important to include reliable sources in your research. Without reliable sources, readers may question the validity of your argument and your paper will not achieve its purpose. Academic research papers are typically based on scholarly sources and primary sources. Scholarly sources include a range of documents, source types, and formats, but they share an important quality: credibility. More than any other source you are likely to encounter during your research, a scholarly source is most likely to be reliable and accurate.
