annotated bibliography and critical preface

Assuming the proposal is the critical preface, there are several parts that a critical preface addresses: Topic, questions, and why it's interesting.  The annotated bibliography explains why each source was chosen and how it will benefit the paper.  This sample is a good example of how to approach writing the preface and bibliography.  However, these examples are missing some parts.  For example, the critical preface doesn't tell how she would research the topic.
