Your annotated bibliography is a preview of the literature review section in your paper. It helps you organize your thoughts and share that information with your professor. Your annotated bibliography shows all of the citations you plan to use and highlights the most important information about those sources.
An annotated bibliography is more than a list of references. The notes you write about each source help you identify why that source is useful to you and help you start to make connections between your sources. What you write also helps your professor understand the choices you have made.
An annotated bibliography is more than a summary of what the source says. You may add a brief summary to set context, but your focus is on how that information will be useful to you.
