  2. Purpose - Why was the source created? Who is the intended audience?
  3. Publication & format - Where was it published? In what medium?
  4. Relevance - How is it relevant to your research? What is its scope?
  5. Date of publication - When was it written? Has it been updated?
  6. Documentation - Did they cite their sources? Who did they cite?
