MLA Annotated Bibliography Format With a Full Worked Sample

What an MLA Annotated Bibliography Looks Like

An MLA annotated bibliography is a Works Cited list where each entry is followed by a short paragraph, called an annotation, that summarizes the source and explains why it is relevant to your project. The citation uses exactly the same format as a standard MLA Works Cited entry, double spaced with a hanging indent, and the annotation sits directly below it, indented to match the continuation lines of the citation.

If you are still building your understanding of what an annotated bibliography is before you worry about formatting, the post on how to write an annotated bibliography from scratch covers that ground. If your course uses APA instead of MLA, the APA annotated bibliography guide is the one to read. This post is specifically for MLA.

A Complete Worked Entry

Here is one full entry as it would appear on the page. Below it, each part is explained.

Sullivan, Andrew. The Abolition of Sex: How the ‘Transgender’ Agenda Harms Women, Girls, and Everyone Else. Encounter Books, 2022.

    Sullivan is a journalist and cultural commentator who has written about gender policy for several decades. This book argues that the legal redefinition of sex to include gender identity creates conflicts with protections that were built around biological sex, particularly in competitive sport and single-sex spaces. Sullivan draws primarily on case law, government policy documents, and statistical data from several Western countries. His argument is openly polemical, which means the book functions less as neutral analysis and more as an advocacy text, and a reader should weigh its claims against peer-reviewed research in sociology and medicine. For a research paper examining tensions within contemporary civil rights law, this source is useful precisely because it represents one side of the debate clearly, and its footnotes point toward primary sources that are independently worth reading.

The author’s name is inverted, last name first, followed by a period. The title of the book is italicized. Publication details come next, in the order publisher then year, separated by a comma. The whole citation ends with a period. Then, on the very next line, the annotation begins at the same indentation as the continuation lines of the citation, which is half an inch in from the left margin.

The annotation itself does three things. The first sentence establishes who the author is and why that matters. The second or third sentence gives the core argument of the source. After that comes a note on method or evidence. The annotation closes with an honest assessment of the source’s limitations and a sentence explaining what it contributes to a specific project. Those last two moves are where students most often fall short, and they are also what separates a useful annotation from a book report summary.

A first attempt usually reads something like this: “This book is about the debate over gender identity. Sullivan thinks that changing the definition of sex is harmful. He uses many examples. This source will be helpful for my paper.”

The trouble is that none of those sentences does any critical work. The annotation tells a reader nothing they could not get from a blurb. A marker reading it learns that you found the source, not that you understood it. The revision in the example above names the method (case law, policy documents, statistical data), identifies a limitation (the polemical stance), and explains exactly what role the source plays in the project (it represents one side of the debate and its footnotes are a secondary benefit). That specificity takes the same number of sentences but earns the marks.

What Changes Depending on Your Situation

The citation format stays the same regardless of level. A freshman writing a five-source bibliography and a doctoral candidate writing a forty-source one both use hanging indents, double spacing, and alphabetical order. What changes is the annotation.

At introductory level, most instructors want a summary plus one sentence of evaluation. Roughly 100 words per annotation is typical. At upper-division or graduate level, the expectation shifts toward evaluation and synthesis: how does this source’s argument relate to the next one on the list? Where do they agree, and where does one complicate the other? An annotation at that level can run to 200 words without feeling padded, because there is genuine analytical work filling the space.

Discipline matters too. A literature course will expect you to say something about the author’s critical framework, whether they are working from a psychoanalytic reading or a historicist one. A history course will push you toward questions of evidence and methodology. A sociology course may want you to note sample size, research design, and whether the source is peer reviewed. The words “this source is relevant to my paper” satisfy none of those expectations. You need the discipline-specific vocabulary your course has been building all semester.

Page counts matter in a practical sense. An annotated bibliography with fifteen entries and 150-word annotations runs to roughly 2,250 words of annotation alone, before the citations. Start early. The writing is not hard, but fifteen individual evaluations done the night before the deadline will all start to sound the same.

Mistakes That Show Up Most Often

The hanging indent disappears. Students set the whole entry at the left margin and the whole annotation at the left margin too, treating the annotation as a freestanding paragraph. In MLA, the annotation is indented to match the second and subsequent lines of the citation. If you are unsure how to set this in Word or Google Docs, use the ruler to set a first-line indent of zero and a left indent of 0.5 inches for the paragraph, then manually pull the first line of the citation back to the margin using a negative first-line indent of -0.5 inches. That produces the hanging indent for the citation and leaves the annotation correctly indented.

The annotation summarizes and stops. Evaluation is half the task. Say whether the source is peer reviewed, whether the author has relevant expertise, whether the data is current enough for your argument to hold, and what the source cannot tell you.

Italics drop off article titles. Book titles, film titles, and journal names are italicized in MLA. Article titles go inside quotation marks. Swapping those two is one of the most common formatting errors in submitted work.

The list is not alphabetized. It sounds elementary, but under deadline pressure, sources get added in the order you found them and nobody re-sorts before submission.

Dates are missing or wrong. MLA 9 requires the access date for online sources that do not carry a publication date, and requires the most recent update date when one is available. Check each entry before you submit.

Where to Go From Here

Read the entry above once more and check your own draft against it line by line. Hanging indent, double spacing, alphabetical order, italics in the right places, and an annotation that names the method, flags a limitation, and explains the source’s specific role in your project. If all of that is present, your bibliography is in good shape.

If the bibliography is one piece of a larger project that is running short on time, we write annotated bibliographies as one of the 49 paper types available across the order form. You pick the type, subject, quality tier, and deadline, and the form calculates the price live. Short work can be turned around in as little as three hours. See how the process works or check current pricing before you place an order. What you receive is model and reference work, intended for research and reference purposes as our terms and conditions explain, and you have 14 days of free revisions after first delivery.
