Annotated Bibliography Example: APA, MLA, and Chicago Formats (2026)
An annotated bibliography example is the fastest way to understand what this often-misunderstood assignment actually requires. Unlike a standard reference list, an annotated bibliography pairs each citation with a brief annotation — a paragraph that summarises the source, evaluates its methodology and credibility, and explains its relevance to your research. This guide provides fully worked examples in APA 7th edition, MLA 9th edition, and Chicago style, with formatting rules, annotation templates, and common mistakes to avoid.
Annotated bibliographies are assigned at undergraduate and postgraduate level for two reasons: they develop your critical reading skills before you write a literature review, and they demonstrate to your supervisor or marker that you have engaged meaningfully with your sources rather than collecting citations superficially. Knowing the correct format for each style — and what a strong annotation actually says — is the difference between a task completed and a task completed well.
What Is an Annotated Bibliography?
An annotated bibliography is a list of citations to books, articles, and other sources. Each citation is followed by a brief (usually 150–300 word) descriptive and evaluative paragraph — the annotation. The annotation tells the reader what the source contains, how it was produced, and why it is relevant to the research at hand.
It differs from a standard reference list (which simply lists sources) and from a literature review (which synthesises multiple sources into a coherent argument). Think of an annotated bibliography as the foundation you build before writing a literature review: it ensures you have read and critically assessed each source individually before weaving them together.
Who Assigns Annotated Bibliographies?
Annotated bibliographies are typically assigned: as a standalone coursework task, as part of a research proposal, as a preliminary step before a dissertation literature review, or as formative feedback tools to check that students are engaging with sources critically.
APA 7th Edition Annotated Bibliography Examples
APA Formatting Rules
- Double-space the entire document (including within and between entries)
- Use a hanging indent (0.5 inch) for each citation line
- Indent the annotation 0.5 inch from the left margin (flush with the hanging indent)
- Entries listed alphabetically by the first author’s surname
- No additional line break between the citation and the annotation
APA Example 1: Journal Article
Orben, A., & Przybylski, A. K. (2019). The association between adolescent well-being and digital technology use. Nature Human Behaviour, 3(2), 173–182. https://doi.org/10.1038/s41562-018-0506-1
This article presents a multiverse re-analysis of three large datasets — the Millennium Cohort Study, the Understanding Society survey, and the US Monitoring the Future survey — to examine associations between digital technology use and adolescent well-being. Using a specification curve approach, the authors demonstrate that the association between technology use and well-being is small (β = −.05) and comparable in magnitude to effects of wearing glasses or eating potatoes — a finding that directly challenges the widely reported “screen time crisis” narrative. The methodological strength of this study lies in its transparency: all 40,000 analytic decisions in the specification curve are reported, reducing researcher degrees of freedom. The study is highly credible given its peer-reviewed publication in Nature Human Behaviour and the authors’ standing (Przybylski is Director of Research at the Oxford Internet Institute). For this dissertation, the article provides a critical methodological counterpoint to studies reporting large negative effects of social media, and its operationalisation of “technology use” as distinct from social media specifically informs the current study’s focus on platform-specific, active/passive use distinctions.
APA Example 2: Book Chapter
Bhabha, H. K. (1994). Of mimicry and man: The ambivalence of colonial discourse. In The location of culture (pp. 121–131). Routledge.
This chapter, from Bhabha’s foundational post-colonial theory collection, develops the concept of “colonial mimicry” — the way in which the colonised subject is required to imitate the coloniser while remaining “not quite / not white,” producing an ambivalence that simultaneously sustains and destabilises colonial authority. Bhabha draws on psychoanalytic theory, particularly Lacan, and on close readings of colonial administrative discourse, to argue that mimicry is not merely a subordination strategy but a site of colonial anxiety and slippage. The argument is theoretically sophisticated but stylistically dense; the chapter is best read alongside Bhabha’s explanatory introduction to the volume. This source is foundational to the theoretical framework of this dissertation, which uses the concept of ambivalence to analyse how post-independence Kenyan public architecture simultaneously rejects and reproduces colonial spatial aesthetics. While Bhabha’s theory was developed primarily through literary and psychoanalytic analysis, its application to architectural production requires adaptation — an adaptation this dissertation contributes.
APA Example 3: Government Report
Department for Education. (2023). Special educational needs and disabilities: Statistics 2022/23. UK Government. https://www.gov.uk/government/statistics/special-educational-needs-in-england
This annual statistical release from the Department for Education reports figures on special educational needs (SEN) provision in England, including the number of children with Education, Health and Care (EHC) Plans, the primary types of need recorded, and the placement settings of children with SEN. The 2022/23 release records that 34% of children with EHC Plans have autism spectrum disorder (ASD) as their primary need — the highest single category. As a government statistical publication, this source has high authority and currency (published annually). The data is collected from all state-funded schools in England, making it a near-complete census rather than a sample, which maximises its reliability. For this dissertation, the 34% figure provides the epidemiological context for investigating ASD-specific inclusive education practices — it establishes that ASD is not a niche concern but the dominant special educational need in English schools.
MLA 9th Edition Annotated Bibliography Examples
MLA Formatting Rules
- Double-space the entire document
- Use a 1-inch hanging indent for the annotation (note: this is 0.5 inch more than APA)
- Use standard MLA hanging indent (0.5 inch) for the citation itself
- Title the page “Annotated Works Cited” (not “Works Cited” or “References”)
- Entries listed alphabetically
MLA Example 1: Journal Article
Myers, Garth Andrew. “Designing Power: Forms and Purposes of Colonial Model Neighbourhoods in British Africa.” Habitat International, vol. 27, no. 2, 2003, pp. 193–204.
Myers examines colonial urban planning in British Africa through a comparative analysis of model neighbourhood schemes in Zanzibar, Lusaka, and Nairobi, arguing that colonial planners used spatial design as a technology of racial segregation and administrative control rather than as a response to organic urban need. Drawing on archival sources from the Public Record Office and on-site fieldwork, Myers traces how the physical layout of streets, housing densities, and amenity provision inscribed racial hierarchies into the built environment. The argument is persuasively evidenced and written with admirable clarity for a theoretically sophisticated piece. The Nairobi case study (pp. 200–203) is of direct relevance to this dissertation, providing baseline evidence of colonial spatial logic against which post-independence architectural choices can be evaluated. Myers’s focus ends at independence, however, which is precisely where the present study begins — making this a foundational but explicitly bounded source.
MLA Example 2: Book
Twenge, Jean M. iGen: Why Today’s Super-Connected Kids Are Growing Up Less Rebellious, More Tolerant, Less Happy — and Completely Unprepared for Adulthood. Atria Books, 2017.
Twenge draws on large-scale survey data from the Monitoring the Future study and the American Freshman Survey to argue that the generation born 1995–2012 — “iGen” — shows dramatically higher rates of depression, anxiety, and loneliness than preceding generations, and that this shift correlates with the rise of smartphones and social media use from around 2012. The book is written for a general audience and is engaging and clearly evidenced. Its core limitation, widely noted in subsequent academic literature (Orben & Przybylski, 2019), is that it conflates correlation with causation and does not adequately control for confounding variables. For this dissertation, Twenge’s work is valuable as a prominent example of the popular narrative around social media and youth mental health — a narrative this study seeks to test more rigorously. It should not be cited as primary empirical evidence but as a cultural-scientific framing device.
Chicago Style Annotated Bibliography Examples
Chicago Notes-Bibliography System: Formatting Rules
- Use the Notes-Bibliography (NB) system for humanities; Author-Date for sciences
- Single-space within entries; double-space between entries
- Use a 0.5-inch hanging indent for the citation
- Indent the annotation 0.5 inch from the left margin (same as APA)
- Title the page “Annotated Bibliography”
Chicago NB Example: Book
Said, Edward W. Orientalism. New York: Pantheon Books, 1978.
Said’s Orientalism is the foundational text of post-colonial studies, arguing that Western representations of the “Orient” — in literature, art, scholarship, and journalism — constitute a knowledge-power formation through which the West has constructed, dominated, and managed the East. Said draws on Foucault’s concept of discourse to analyse a wide range of canonical European texts, demonstrating that the “Orient” was never an objective geographic entity but a Western construction that served imperial political purposes. The argument has been influential across disciplines — literary studies, history, geography, architecture — and has attracted both enthusiastic adoption and significant critique, particularly for its tendency to homogenise both “East” and “West.” For this dissertation, Said’s framework underpins the theoretical approach to reading colonial architecture as a discourse of power rather than as neutral aesthetic production. His work predates the post-independence period that this study examines, but it provides the conceptual vocabulary — particularly the relationship between knowledge, representation, and power — through which the architectural evidence is interpreted.
3 Types of Annotation — Summary, Evaluative, and Combined
| Type | What It Does | When It Is Used |
|---|---|---|
| Summary | Describes the main argument and scope of the source only | Early-stage research; some library assignments |
| Evaluative | Assesses the quality, credibility, and limitations of the source | Critical thinking exercises; some postgraduate work |
| Combined (most common) | Summarises, evaluates, AND explains relevance to your specific project | Most university annotated bibliography assignments |
Unless your assignment specifies otherwise, write a combined annotation. All examples above are combined annotations.
How to Write an Annotation: Template and Formula
Use this three-part structure for every annotation:
- Summary sentence (1–3 sentences): “This [article/book/report] [argues/reports/demonstrates] that [main finding or argument]. The author uses [method/source material] to [how they build the argument].”
- Evaluation (2–3 sentences): “The [strength/credibility] of this source lies in [peer-review status / sample size / theoretical rigour / archival depth]. A limitation is [methodological weakness / dated evidence / scope restriction / potential bias].”
- Relevance to your project (1–2 sentences): “For this dissertation, the source is relevant because [specific connection to your research question]. It will be used to [specific purpose in your argument].”

8 Common Annotated Bibliography Mistakes
- Writing only a summary. Most assignments require evaluation. Summarising without assessing quality or relevance earns only partial credit.
- Wrong indent for annotations. MLA uses a 1-inch indent for annotations — not the 0.5 inch used in APA and Chicago. This is the most frequent formatting error.
- Including sources you haven’t critically read. Annotations must reflect actual engagement with the source. Supervisors often spot annotations based on abstracts alone.
- Generic relevance statements. “This source is relevant to my topic” says nothing. Name your specific research question and explain precisely how the source addresses it.
- Incorrect citation format. The citation must be formatted exactly as in a standard reference list. A common error is using APA in-text format (Author, Year) inside the annotation text — annotations use the full author name in prose.
- Evaluating by reputation alone. “This is a reliable source because it was published in a peer-reviewed journal” is a start, but strong evaluation also notes methodological approach, sample, and specific limitations.
- Annotations of equal length for unequal sources. A foundational 400-page book should typically receive a longer annotation than a 4-page newspaper article. Calibrate length to the source’s centrality to your project.
- Failing to note limitations. Every source has limitations. Noting them shows critical thinking and protects you from over-relying on a single source in your literature review.

Frequently Asked Questions
What is the difference between an annotated bibliography and a reference list?
A reference list (or Works Cited / Bibliography) is a formatted list of all sources cited in your work — it contains only the citation, with no commentary. An annotated bibliography adds a descriptive and evaluative paragraph (the annotation) after each citation, explaining what the source contains and why it is relevant. An annotated bibliography is an assignment in itself; a reference list appears at the end of every research paper, essay, and dissertation automatically.
How long should an annotated bibliography be?
The total length of an annotated bibliography depends on how many sources are included and the required annotation length. A typical undergraduate assignment might require 8–12 sources with 150–200 word annotations each, totalling 1,500–2,400 words of annotation text. At postgraduate level, 15–30 sources with 200–300 word annotations is common. Always check your assignment brief, as required source numbers and annotation lengths vary significantly between instructors and institutions.
Should annotations be written in first person?
Conventions vary. In APA style, first-person is now acceptable in academic writing (APA 7th edition allows “I” and “we”). In MLA and Chicago, first-person is generally acceptable in annotated bibliographies for the relevance section (“This source is relevant to my dissertation because…”), though some instructors prefer third-person throughout. When in doubt, use first-person for your relevance statement (“This source informs my…”) and third-person for the summary (“The authors argue that…”). Check your institution’s style guide or ask your supervisor.
Can I include websites in an annotated bibliography?
Yes, websites can be included, but they require more careful evaluation than peer-reviewed sources. Your annotation should assess the credibility of the author or organisation, the currency of the information, whether the site has editorial review processes, and any potential bias. Government websites, established NGOs, major news organisations, and official statistical bodies are generally credible. Personal websites, Wikipedia, and commercial content marketing should typically be avoided as primary sources in academic annotated bibliographies.
Does an annotated bibliography count toward my word count?
This depends entirely on your institution’s word count policy. In most UK universities, reference lists and bibliographies are excluded from word counts, but annotations — because they are analytical writing — are typically included. If your annotated bibliography is a standalone assignment, the entire document (citations + annotations) usually counts toward the word limit. Always check your assignment brief or module handbook for your specific institution’s rules.
