Knowing how to cite sources makes an essay easier to verify, protects you from accidental plagiarism, and shows how your ideas connect to existing research. This reusable checklist explains MLA and APA citations for common source types, highlights the details to double-check, and gives you a practical review routine before submitting an assignment.
Overview
Before creating a citation, identify two separate parts of documentation: the in-text citation and the full reference entry. The in-text citation briefly directs the reader to the source at the point where you use an idea, quotation, statistic, image, or other borrowed material. The Works Cited entry in MLA or the reference-list entry in APA provides enough information for the reader to locate that source.
MLA is commonly used in language, literature, and humanities assignments. Its in-text system usually emphasizes the author’s name and a page number when one is available. APA is widely used in social sciences and other fields that value the date of publication. Its in-text system normally includes the author and year, with a page or paragraph locator for a direct quotation.
Your instructor’s directions take priority over a general citation guide. Course requirements may specify a particular edition, heading format, database treatment, or approach to sources with missing information. A citation generator can save time, but it cannot reliably decide whether the information entered is complete or whether your source actually supports the claim. Treat generated citations as drafts to inspect.

Checklist by scenario
1. Book
Record the author, title, edition if it is not the first, publisher, publication year, and any relevant volume or translator information.
MLA example: Morrison, Toni. Beloved. Vintage International, 2004.
APA example: Morrison, T. (2004). Beloved. Vintage International.
For an in-text reference, MLA commonly uses the author’s surname and page number: (Morrison 72). APA commonly uses the surname and year: (Morrison, 2004). Add a page number when quoting directly: (Morrison, 2004, p. 72).
2. Web page
Capture the author or organization, page title, website name, publication or update date, and stable URL. If no date is shown, use the format required by the style and your instructor rather than guessing a date.
MLA example: United Nations. “Sustainable Development Goals.” United Nations, www.un.org/sustainabledevelopment/sustainable-development-goals/.
APA example: United Nations. (n.d.). Sustainable development goals. https://www.un.org/sustainabledevelopment/sustainable-development-goals/
Check the page itself before citing it: confirm the author, title, date, and URL. A search-result snippet is not a substitute for reading the source.
3. Journal article
Save the article’s authors, title, journal name, volume, issue, page range, publication year, and DOI if one is provided. A DOI is usually preferable to a long database or session-specific URL.
MLA pattern: Author Last Name, First Name. “Article Title.” Journal Title, vol. number, no. number, year, pp. xx–xx. DOI or URL.
APA pattern: Author, A. A. (Year). Article title. Journal Title, volume(issue), xx–xx. https://doi.org/xxxxx
Do not assume that every web page is a journal article. Look for publication details, a journal title, volume or issue information, and page numbers or an article number.
4. Online video
Identify the creator or account responsible for the video, its title, platform, upload date when available, and direct URL. The creator may be an individual, organization, or channel.
MLA pattern: Creator or Channel. “Video Title.” Platform, upload date, URL.
APA pattern: Creator or Channel. (Year, Month Day). Video title [Video]. Platform. URL
Cite the specific video you watched, not merely the channel homepage. For a quotation from a video, use a timestamp when page numbers are unavailable, following the conventions required by your style guide.
5. AI-assisted research
First, check your instructor’s rules before using generative AI in research or writing. Keep a record of the tool, date, prompt or relevant interaction, and the output you relied on. Do not treat an AI response as proof that a source exists. Verify every quotation, URL, statistic, and factual claim against an authoritative source.
MLA and APA treatment of AI-generated text can depend on how the tool was used and on the applicable style guidance. If AI helped brainstorm, summarize, translate, or generate text, explain that use when required. If you cite an AI output, identify the tool and provide the information your instructor or style guide requests. A separate citation may still be needed for the original article, book, or webpage behind the idea.

What to double-check
- Author: Use the source’s listed author or organization. Do not use a search engine, database, or publisher as the author unless that entity actually created the work.
- Title: Copy the title accurately, including subtitles. Apply italics, quotation marks, and capitalization according to MLA or APA rules.
- Date: Use the publication or update date shown on the source. Never invent a date from the date you accessed the page.
- Location information: Confirm page numbers, volume and issue numbers, article numbers, DOI links, or URLs.
- In-text connection: Make sure every in-text citation points clearly to one Works Cited or reference-list entry, and that every cited entry is used in the essay unless your assignment asks for a broader bibliography.
- Direct quotations: Add the required locator, such as a page number, paragraph number, chapter, section, or timestamp when appropriate.
- Source quality: Read enough of the original source to confirm that it supports your sentence. Citation correctness cannot repair a misleading or irrelevant source.
- Formatting: Check hanging indents, alphabetical order, spacing, punctuation, and the required document layout. Use your instructor’s directions if they differ from a general template.
Common mistakes
Copying a citation without checking it. Databases and citation generators may omit an editor, mislabel a date, use the wrong URL, or format a title incorrectly. Compare the generated entry with the source record.
Confusing a citation with a bibliography. A Works Cited or reference list should reflect the documentation system your assignment requests. Do not combine MLA and APA conventions because a source appears in both styles online.
Using one format for every source. A book, webpage, journal article, and video require different details. Start with the source type, then apply the appropriate pattern.
Adding a citation only after a quotation. Paraphrased ideas, distinctive facts, data, images, and summaries also need attribution. Changing a few words does not make someone else’s idea your own.
Citing a source you did not read. If you discovered an idea in a review or article that refers to an original study, cite the source you actually consulted and follow the rules for secondary sources if your assignment permits them.
Ignoring plagiarism during revision. Keep source notes separate from your own draft, mark copied wording in quotation marks immediately, and use a plagiarism checker as a self-review tool, not as a replacement for careful attribution.
When to revisit
Use this checklist whenever you begin a research assignment, change citation style, add a new source type, or revise an essay after instructor feedback. Revisit it before submission, especially if you imported citations from a database, used online media, or worked with an AI tool.
It is also worth checking the relevant style guide when a new edition is required, your school updates its writing instructions, or a course gives source-specific rules. Citation practices can vary by assignment even when the general MLA or APA pattern looks familiar.
Before uploading your final file, complete this five-minute routine:
- Highlight every quotation, paraphrase, summary, image, and borrowed fact.
- Confirm that each highlighted item has an appropriate in-text citation.
- Match each in-text citation to a complete Works Cited or reference-list entry.
- Open important links and verify authors, dates, titles, and locators.
- Read the assignment instructions once more for required style, edition, and formatting details.
Save the final source list with your notes so that future revisions are easier. If citation work is one part of a larger study routine, combine it with a realistic study schedule and leave time for verification rather than treating citations as a last-minute formatting task.
