Your instructor may ask you to use only scholarly resources for your paper. What's the difference between a scholarly or non-scholarly resource?
Scholarly (peer-reviewed) sources include books and articles published in scholarly journals, encyclopedias, and books. These sources are reviewed by a panel of experts in that particular field and are often published by a professional association or a university press. These experts ensure the information published is credible before accepting it for publication.
Non-Scholarly sources include websites, magazines, newspapers, and books that undergo no expert review prior to publishing.
Check with your instructor if you plan to use any non-scholarly websites.
