There are a few ways to generate citations.
1. NoodleTools will give you a form to fill out that generates a citation from the information you give it. You just need the right information!
2. Zbib will take a URL, ISBN, DOI, PubMed number, or the title of your article or book and then scour the internet until it can generate a citation in your preferred format.
3. Many databases have a citation generator! Look for the Cite button and then select your format.
Remember: Always double-check your citations! Citation generators can be fast and easy, but sometimes they're wrong. Make sure the citations are correct before you turn in your paper.
