What is an Annotated Bibliography?
An annotated bibliography is a structured list of sources. It consists of two parts:
- The Citation: The bibliographic information is formatted according to a specific style (APA, MLA, etc.).
- The Annotation: A paragraph (usually 100-200 words) that summarizes, assesses, and reflects on the source.
Why Do Professors Assign It?
- To Review the Literature: It proves you have done the reading.
- To Develop Critical Skills: It tests your ability to judge the quality of a source.
- To Focus the Research: It prevents you from collecting irrelevant sources.
The 3 Types of Annotations
Before you write, you must know what kind of annotation your professor wants.
1. Descriptive / Informative
This type simply summarizes the source. It answers the question: "What is the main argument?" It does not judge the quality. It is like an abstract.
2. Analytical / Critical
This is the most common type for university assignments. It summarizes the source and evaluates it. It answers: "Is the methodology sound? Is the author biased? Is it useful for my paper?"
3. Combination
This combines a summary with a brief evaluation. It is often required for comprehensive research projects.
If you are unsure which type you need, our custom annotated bibliography online writing service can analyze your assignment brief to ensure you hit the right tone.
Step-by-Step: Writing the Annotation
Writing an annotation requires a formula. Follow these three steps for every single source.
Step 1: Summarize
What is the source about?
- Example: "In this article, Smith (2020) investigates the impact of remote work on employee productivity. Using a survey of 500 tech workers, he argues that flexibility increases output."
Step 2: Assess / Evaluate
Is it a good source?
- Example: "Smith’s methodology is robust, utilizing a large sample size. However, the study is limited to the tech sector, meaning the findings may not apply to manual industries."
Step 3: Reflect
How does it fit into your research?
- Example: "This article provides key statistical evidence for my argument that remote work policies should be permanent. It contradicts the earlier findings of Jones (2018)."
Formatting: APA vs. MLA vs. Chicago
The content is important, but the format is vital. The "Hanging Indent" is your nemesis here.
APA Style (Social Sciences)
- Citation: Author, A. A. (Year). Title of book. Publisher.
- Annotation: The entire paragraph is indented 0.5 inches from the left margin.
MLA Style (Humanities)
- Citation: Author, First Name. Title of Book. Publisher, Year.
- Annotation: Also uses a hanging indent. Double-spaced.
Chicago Style (History)
- Citation: Author, First Name. Title of Book. Place: Publisher, Year.
- Annotation: Formatting varies (Author-Date vs. Notes-Bibliography).
If you are struggling with hanging indents or the specific punctuation rules, our annotated bibliography service experts can format your entire document perfectly.
Common Mistakes to Avoid
1. Just Copying the Abstract
Do not copy the abstract from the journal. That is plagiarism. You must read the article and summarize it in your own words. The abstract tells you what the author thinks they did; your annotation tells us what they actually achieved.
2. Being Too Vague
Avoid phrases like "This book was interesting" or "This article is good." Be specific. "This book provides a comprehensive history of the Civil War" is better. "This book challenges the revisionist narrative of the Civil War" is best.
3. Ignoring the "So What?"
If you don't explain why the source is relevant to your specific research question, the annotation is useless. It must link back to your project.

Frequently Asked Questions
How many sources should I include?
This depends entirely on your assignment brief. For a short undergraduate assignment, it might be 5-10 sources. For a dissertation proposal, it could be 20+. Always check with your professor. A good rule of thumb is to ensure you have a mix of primary and secondary sources to show breadth of research.
Can I use the same sources in my final essay?
Yes, that is the point! The annotated bibliography is preparation for your final paper. You have already done the reading and the evaluation, so when you write the essay, you can simply pull the arguments from your bibliography. It saves you massive amounts of time later.
Do I need to read the whole book for an annotation?
Ideally, yes. However, for a long book, you can often get a good sense of the argument by reading the Introduction, the Conclusion, and key chapters relevant to your topic. For journal articles, you should read the whole thing, focusing on the Methodology and Discussion sections.
Can I use "I" in my annotations?
In some styles, yes. If you are writing a "Reflective" annotation (explaining how the source helps your research), using "I" is appropriate (e.g., "I will use this source to support my argument that..."). However, for descriptive annotations, stick to the third person. Check your module handbook.
Can I buy an annotated bibliography online safely?
Yes, if you use a reputable service like My Perfect Writing. We provide custom-written models that you can use as study guides. It helps you understand how to critique sources and structure your own work. Our buy annotated bibliography online service is confidential and secure.
