Good sources enhance the credibility and persuasiveness of an argument, while a source that lacks credibility can destroy it. Use the following criteria to ensure your source is a good one:
Currency:
- When was the information published or posted?
- Has the information been revised or updated?
- Is the information current or out-of-date for your topic?
Relevance:
- Does the information relate to your topic or answer your question?
- Have you looked at a variety of sources before determining this is the one you will use?
Authority:
- Who is the author/publisher/source?
- What are the author's qualifications to write on the topic?
- Is there contact information, such as a publisher or email address?
- What does the URL extension reveal about the author or source? (.com, .edu, .gov, .org)
Accuracy:
- Does the author cite their sources?
- Is the information supported by evidence?
- Has the information been reviewed or refereed?
Purpose:
- Do the authors/sponsors make their intention or purpose clear?
- Is the information Fact? Opinion? Propaganda?
