I am supposed to be doing an annotated bibliography on the following two articles regarding postpartum depression and I am not too sure where to start or what to include in it. I have never done an annotated bibliography, so this is a foreign language to me right now.

How do I know what theory was used?

Any help would be appreciated.

Thank you
