An annotated citation has two parts:

1. The citation should be in the style you've been assigned (MLA, Chicago, APA, etc).
    
2. The annotation includes a summary and/or evaluation of each of your sources. It may include any or all of these 3 sections, depending on your assignment requirements:

• Summary: Summarize the source. What are the main arguments? What is the point of this book or article? What topics are covered? If someone asked what this article/book is about, what would you say?
   
• Assessment: After summarizing a source, it may be helpful to evaluate it. Is it a useful source? How does it compare with other sources in your bibliography? Is the information reliable? Is this source biased or objective? What is the goal of this source?
   
• Reflection: Once you've summarized and assessed a source, you need to ask how it fits into your research. Was this source helpful to you? How does it help you shape your argument? How can you use this source in your research project? Has it changed how you think about your topic?
