How to Write an Annotated Bibliography - APA Style (7th Edition)

What is an annotation?

An annotation is more than just a brief summary of an article, book, website, or other type of publication. An annotation should give enough information to make a reader decide whether to read the complete work. In other words, if the reader were exploring the same topic as you, is this material useful and if so, why?

How is an annotation different from an abstract?

While an abstract also summarizes an article, book, website, or other type of publication, it is purely descriptive. Although annotations can be descriptive, they also include distinctive features about an item. Annotations can be evaluative and critical as we will see when we look at the two major types of annotations.

What is an annotated bibliography?

An annotated bibliography is an organized list of sources (like a reference list). It differs from a straightforward bibliography in that each reference is followed by a paragraph length annotation, usually 100–200 words in length.

Depending on the assignment, an annotated bibliography might have different purposes:

  • Provide a literature review on a particular subject
  • Help to formulate a thesis on a subject
  • Demonstrate the research you have performed on a particular subject
  • Provide examples of major sources of information available on a topic
  • Describe items that other researchers may find of interest on a topic

Types of annotated bibliographies

There are two major types of annotated bibliographies:

  1. Descriptive or informative
  2. Analytical or critical

Descriptive or informative

A descriptive or informative annotated bibliography describes or summarizes a source as does an abstract; it describes why the source is useful for researching a particular topic or question and its distinctive features. In addition, it describes the author's main arguments and conclusions without evaluating what the author says or concludes.

For example:

McKinnon, A. (2019). Lessons learned in year one of business. Journal of Legal Nurse Consulting30(4), 26–28.
This article describes some of the difficulties many nurses experience when transitioning from nursing to a legal nurse consulting business. Pointing out issues of work-life balance, as well as the differences of working for someone else versus working for yourself, the author offers their personal experience as a learning tool. The process of becoming an entrepreneur is not often discussed in relation to nursing, and rarely delves into only the first year of starting a new business. Time management, maintaining an existing job, decision-making, and knowing yourself in order to market yourself are discussed with some detail. The author goes on to describe how important both the nursing professional community will be to a new business, and the importance of mentorship as both the mentee and mentor in individual success that can be found through professional connections. The article’s focus on practical advice for nurses seeking to start their own business does not detract from the advice about universal struggles of entrepreneurship makes this an article of interest to a wide-ranging audience.

Analytical or critical

An analytical or critical annotation not only summarizes the material, it analyzes what is being said. It examines the strengths and weaknesses of what is presented as well as describing the applicability of the author's conclusions to the research being conducted.

Analytical or critical annotations will most likely be required when writing for a college-level course.

For example:

McKinnon, A. (2019). Lessons learned in year one of business. Journal of Legal Nurse Consulting30(4), 26–28.
This article describes some of the difficulty many nurses experience when transitioning from nursing to a nurse consulting business. While the article focuses on issues of work-life balance, the differences of working for someone else versus working for yourself, marketing, and other business issues the author’s offer of only their personal experience is brief with few or no alternative solutions provided. There is no mention throughout the article of making use of other research about starting a new business and being successful. While relying on the anecdotal advice for their list of issues, the author does reference other business resources such as the Small Business Administration to help with business planning and professional organizations that can help with mentorships. The article is a good resource for those wanting to start their own legal nurse consulting business, a good first advice article even. However, entrepreneurs should also use more business research studies focused on starting a new business, with strategies against known or expected pitfalls and issues new businesses face, and for help on topics the author did not touch in this abbreviated list of lessons learned.

To get started

Now you are ready to begin writing your own annotated bibliography.

  • Choose your sources - Before writing your annotated bibliography, you must choose your sources. This involves doing research much like for any other project. Locate records to materials that may apply to your topic.
  • Review the items - Then review the actual items and choose those that provide a wide variety of perspectives on your topic. Article abstracts are helpful in this process.
  • Write the citation and annotation - When writing your annotation, the complete citation should always come first and the annotation follows. Depending on the type of annotated bibliography you are writing, you will want to include some or all of the following:
    • The purpose of the work
    • A summary of its content
    • Information about the author(s)
    • For what type of audience the work is written
    • Its relevance to the topic
    • Any special or unique features about the material
    • Research methodology
    • The strengths, weaknesses or biases in the material

Annotated bibliographies may be arranged alphabetically or chronologically, check with your instructor to see what he or she prefers.
