|The 5 Ws
|The Surface-Level Questions
|The Deeper Questions
Who is the author, editor, or creator? Is the author qualified to write about this topic?
|What makes them qualified? First-hand experience? An advanced degree?
What type of document is it? For example, is it a newspaper article? A blog? A government website? A scholarly article? A book?
What is it about?
Is the source appropriate for the type of research you are doing?
Is it relevant to your research?
When was this source published?

Do your best to find the answers to these questions. Use these questions to help answer the broader question: Is this source appropriate to use for the research that I am conducting?
