An annotated bibliography is a list of things you've read in a standard citation format (MLA), along with a description of what each source is about and why it matters for your project. You should also include some language about why the sources you're including are, in Dr. J-P's words, "high caliber." What makes them so?
Your bibliography entries should include these main elements:
Full citation in MLA format (written out as for a works cited page)
Brief description of what the source is about (what's the object of analysis? What's the argument? What are the main ideas?)
Identification of source's quality, or some evaluative observations about its claim to value in this case.
Brief explanation of how this piece fits into your work (presentation, background or primary source reading, etc.)
