The Information Cycle

The information cycle is the progression of media coverage of a newsworthy event. Understanding the information cycle can help you determine what kind of information you are likely to find about your topic. This video from UNLV's Lied Library shows how an event can unfold in the information cycle.

What is an annotated bibliography? 

An annotated bibliography a list of sources with accompanying notes and commentary, called annotations, that describe and evaluate the sources. What goes in your annotations will depend on what your instructor requires, or what you're using your notes for. Usually an annotation will include a brief summary of the source and also an evaluative statement. Is this a good source for your project? What is useful about it? What is not useful about it? 

Annotated bibliographies are a big part of research. You have a question that you want answered, and in the course of your research, you may find that you want to go back to a source you previously did not think would be useful. If you have annotations for each source you've found, you'll know exactly which source it was and why it may now be of more use than you thought. 

Purdue OWL gives us some good tips on what questions to ask for our annotations, as well as how to format this type of paper. 

  • Summarize: Some annotations merely 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? The length of your annotations will determine how detailed your summary is.

    For more help, see our handout on paraphrasing sources.

  • Assess: 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?

    For more help, see our handouts on evaluating resources.

  • Reflect: 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?
