MLA format for annotated bibliographies
The list should be titled either “Annotated Bibliography” or “Annotated List of Works Cited.” You may be told which title to use; “bibliography” is normally used for a list that also includes sources you didn’t cite in your paper or that isn’t connected to a paper at all.
Sources are usually organized alphabetically, like in a normal Works Cited list, but can instead be organized chronologically or by subject depending on the purpose of the assignment.
The source information is presented and formatted in the same way as in a normal Works Cited entry:
- 0.5 inch hanging indent
The annotation follows on the next line, also double-spaced and left-aligned. The whole annotation is indented 1 inch from the left margin to distinguish it from the 0.5 inch hanging indent of the source entry.
- If the annotation is only one paragraph long, there’s no additional indent for the start of the paragraph.
- If there are two or more paragraphs, indent the first line of each paragraph, including the first, an additional half-inch (so those lines are indented 1.5 inches in total).
Length and content of annotations
MLA gives some guidelines for writing the annotations themselves. They cover how concise you need to be and what exactly you should write about your sources.
Phrases or full sentences?
MLA states that it’s acceptable to use concise phrases rather than grammatically complete sentences in your annotations.
While you shouldn’t write this way in your main text, it’s acceptable in annotations because the subject of the phrase is clear from the context. It’s also fine to use full sentences instead, if you prefer.
- Broad history of Western philosophy from the ancient Greeks to the present day.
- Kenny presents a broad history of Western philosophy from the ancient Greeks to the present day.
Always use full sentences if your instructor requires you to do so, though.
How many paragraphs?
MLA states that annotations usually aim to be concise and thus are only one paragraph long. However, it’s acceptable to write multiple-paragraph annotations if you need to.
If in doubt, aim to keep your annotations short, but use multiple paragraphs if longer annotations are required for your assignment.
Descriptive, evaluative, or reflective annotations?
MLA states that annotations can describe or evaluate sources, or do both. They shouldn’t go into too much depth quoting or discussing minor details from the source, but aim to write about it in broad terms.
Frequently asked questions about annotated bibliographies
- What is an annotated bibliography?
- What types of sources should I use in an annotated bibliography?
- How do I write an annotation for a source?
The content of the annotation varies according to your assignment. An annotation can be descriptive, meaning it just describes the source objectively; evaluative, meaning it assesses its usefulness; or reflective, meaning it explains how the source will be used in your own research.
