Ideally, everything you find through the library's tools would be legitimate e.g. peer-reviewed and/or scholarly. That is not always the case. Whether you have identified a resource through Google or a scholarly index like Proquest Politics you must critically evaluate every source before you use it.
There are a number of convenient checklists that have been developed to help you evaluate websites. Two of the most well-known checklists are included below: RADAR and CRAAP. Either option provides a list of questions to help you evaluate the information you retrieve from the web, whether scholarly in scope or not.
Option #1 for Evaluating Sources: RADAR
Relevance
- How is this information relevant to your assignment? Does it relate to your research question?
- Consider your audience and compare the information source with a variety of sources.
Authority
- Who is the author?
- What makes this person or organization an authoritative source?
Date
- When was this information published and is the publication date important to you?
Appearance
- Where are they getting their information from?
- Does it have citations and references?
- Are they using reputable sources or explaining how they gathered their data?
Reason for Writing
- The timeliness of the information.
- Is the information biased?

For a handy CRAAP worksheet, refer to this rubric attributed to Central Library MCHS. It prompts you to score a site on each of the CRAAP criteria to come up with a final score that could range between a potentially "highly questionable source" to a "excellent source for research."
