Rules for Citing Websites
- Important Reminder: Use caution when referencing the internet. Many websites are not appropriate/credible sources. Use only the highest quality sites.
- When in doubt, CRAAP test it! CRAAP stands for currency, relevance, accuracy, authority, and purpose. Use these metrics to determine whether or not a website is a good resource for you.
- Authors don't have to be people. If you can't find an individual responsible for the content, look for an organization or corporate author.
