💡 What Is an Annotated Bibliography?

An annotated bibliography is a list of citations (just like in a regular bibliography), but each citation is followed by a short paragraph (called an annotation) that summarizes and evaluates the source.

In short:
Bibliography = Just the source
Annotated Bibliography = Source + your notes about it

Step 3: Write the Annotation

Under your citation, write a paragraph that includes:

1. A summary of the source

2. Your evaluation of its strengths or weaknesses

3. A brief reflection on how it connects to your research

Example Annotation (APA Style):
Smith, J. A. (2020). Climate change and global policy. Academic Press.
This book provides a comprehensive analysis of international climate change policies, focusing on their effectiveness and implementation challenges. The author, a renowned environmental scientist, supports his claims with recent data and case studies. This source will be useful for understanding the global context of climate change policy in my research paper.

Step 4: Format the Document

Each citation should be:

• Alphabetized by the author’s last name

• Double-spaced

• Indented properly (use a hanging indent for the citation, flush left for the annotation)

Make sure everything is consistent in spacing, font, and style guidelines according to the required formatting style.
