Citation and Academic Integrity

Citation gets taught as a rulebook and experienced as a trap—commas in the wrong place, a missing italic, a grade lost to a technicality. That framing is backwards. A citation is a piece of writing that does work: it tells a reader exactly where an idea came from, how far it can be trusted, and where the writer’s own thinking starts. Get that right and the punctuation is a twenty-minute problem you can solve with a template. Get it wrong and no amount of formatting saves the paragraph. This chapter treats citation as a skill with moving parts you can practice: reading a reference entry like a form, matching in-text markers to end-of-paper entries, handling the sources that do not fit the templates, and recognizing the four or five specific ways honest students accidentally plagiarize. Every rule here comes attached to a sentence you can copy, break, and repair.

Section 1What a Citation Is Actually For

Four jobs, none of them decorative

Ask most students why they cite and you get some version of “so I don’t get in trouble.” That is one consequence of citing, but it is not a job. A citation does four things at once, and each one fails in a way a reader can feel.

It credits: it says this sentence contains someone else’s labor. It locates: it gives a reader enough information to find the source in under a minute, which is the real test of a reference entry. It calibrates: a reader who sees a 1987 textbook behind your claim about sepsis management weighs it differently than a 2023 systematic review, and the citation is what lets them do that weighing. And it separates: everything not marked as borrowed is claimed as yours, so citation is the boundary line that makes your original contribution visible at all.

That last job is the one nobody mentions and the one that matters most for your grade. A paper with no citations does not read as brilliantly original. It reads as unsourced, which in college is a synonym for unsupported. Instructors do not count citations to catch cheaters; they read citations to find out what you did with your reading.

Common knowledge is a line drawn by audience, not by fact

The usual advice—“you do not need to cite common knowledge”—is true and nearly useless, because students hear it as a claim about facts. It is a claim about readers. Common knowledge is what your specific audience already accepts without a source. That line moves.

Write for a general first-year audience and “the human heart has four chambers” needs no citation. Write for that same audience and “roughly one in three adults in the United States has high blood pressure” does need one, because the number is contestable, dated, and definition-dependent—roughly a third of adults meet the older 140/90 threshold, while the 130/80 cutoff adopted in the 2017 guideline pushes the share to nearly half. Now write for a cardiology journal, and the four-chambered heart is still uncited but so is a great deal of physiology your composition instructor would flag.

Two practical tests. First, the three-source test: if you can find the fact stated without attribution in three independent general sources, it is probably common knowledge for a general audience. Second, and better: could a skeptical reader ask “says who?” If yes, cite. Numbers, dates, causal claims, anything with a study behind it, and anything you did not know last week almost always fail that test.

Integrity is a professional habit, not a school rule

If you are headed into nursing, respiratory therapy, radiography, or any clinical field, you are about to enter a documentation culture with the same logic and much higher stakes. A chart note attributes: who assessed, who administered, who was notified, at what time. Copying a previous shift’s assessment forward because it “probably has not changed” is the clinical version of patchwriting, and it has killed people. Fabricating a vital sign you did not take is the clinical version of a fabricated source.

This is not a moralizing detour. It is the argument for why the habit is worth building now, while the penalty is a grade rather than a license. The mechanics you practice in a composition course—tracking where information came from, keeping your words separate from someone else’s, refusing to assert what you did not verify—are the same mechanics that make a clinician trustworthy.

Section 2The Anatomy of a Citation

Two halves that must match

Every mainstream style has exactly two moving parts. A short marker interrupts your sentence as briefly as possible: (Okonkwo, 2021). A full entry at the end of the paper gives the reader everything needed to find the thing. The marker is deliberately stingy because a reader in the middle of your argument does not want a publisher’s name; the entry is deliberately complete because a reader hunting the source does.

The rule that follows from this is the single most-violated rule in student writing, and it is mechanical enough to check in ninety seconds: every in-text citation must have a matching entry, and every entry must be cited at least once in the text. An in-text marker with no entry is an orphan; the reader hits a dead end. An entry with no in-text marker is padding, and instructors read it as exactly that—a source added to the list without being used.

One housekeeping note before the examples. The sources named throughout this chapter—Okonkwo, Bell, Vega, the Journal of Nursing Practice—are invented so the patterns stay clean. They are practice fixtures. Do not cite them in a real paper.

Reading a reference entry like a form

A reference entry looks like a wall of punctuation until you notice it is a form with four fields, always in the same order: who, when, what, where. Once you see the fields, you can build an entry for a source type you have never cited before.

Here is an APA 7 journal entry with the fields labeled:

Okonkwo, R. (who) (2021). (when) Schedule volatility and medication error on inpatient units. (what) Journal of Nursing Practice, 12(3), 40–49. https://doi.org/10.0000/jnp.2021.1203 (where)

The field labels are set in bold here purely so you can see the seams; only the journal name and volume number are actually italic in APA.

Notice what APA is doing with capitalization, because it encodes information. The article title is in sentence case—only the first word of the title, the first word of any subtitle after a colon or dash, and proper nouns capitalized—while the journal name is in title case and italicized. That contrast tells a reader at a glance which part is the piece and which part is the container holding it. The volume number is italic; the issue number in parentheses is not. The DOI, a permanent digital identifier, is formatted as a full link. MLA makes the same distinctions with different tools: quotation marks around the article title, italics around the container.

The hanging indent—first line flush left, all following lines indented half an inch—is not decoration either. It pushes every author’s surname into a clean left column so a reader can scan alphabetically. Set it in your word processor’s paragraph dialog, under Special. Do not build it with the tab key; it will collapse the moment anything reflows.

In-text citations, APA and MLA side by side

Both styles lead with the author’s name, then disagree about what a reader needs next to it. APA carries the date, because in the sciences currency is a quality signal. MLA carries a page number, because in literary study the reader is expected to go look at the passage. Neither is arbitrary, and knowing why makes the formatting easier to remember.

Two differences worth internalizing. APA requires a page or paragraph number only for direct quotations, though it encourages one for paraphrase; MLA expects a location for both whenever the source has one. And APA uses an ampersand inside parentheses but the word “and” in running text—(Okonkwo & Bell, 2021) versus Okonkwo and Bell (2021)—a tiny rule that graders notice because it is so easy to get right.

Signal phrases: where the citation meets the sentence

A parenthetical citation dropped at the end of a sentence is legal and often flat. A signal phrase puts the source into the grammar of your sentence, which lets you characterize it while you cite it. Compare:

Notice the verbs. Found, reported, argues, frames, concedes, speculates—each one tells the reader how much weight the source is carrying. “Proves” is almost always wrong. “Says” is almost always weak.

Section 3Building References for Real Sources

Work from templates, not from memory

Nobody memorizes reference formats. Competent writers keep a template file and fill it in. Here are the patterns that cover perhaps ninety percent of undergraduate sources in APA 7, each with a worked example. Build your own version of this table in a document you keep, and add a row every time you hit a new source type.

Three details that trip people constantly. APA 7 dropped publisher location, so no more “New York, NY.” If an article has a DOI, include it whether you read the article in print or online. And if you found an article through a library database but it has no DOI, APA treats it as if you read it in the journal—you do not name the database, because the database is how you got there, not what you read.

The hard cases, and what to do about each

Templates cover the easy ninety percent. The remaining ten percent is where students freeze and then guess, and guessing is what produces the entries that look obviously wrong.

No author. Move the title into the author slot and alphabetize by it, ignoring an initial A, An, or The. In text, shorten the title and match how the entry formats it: quotation marks for a piece inside a larger work, italics for a standalone work. If the journal article and the web page above carried no byline, they would appear as (“Reporting Culture on Night Units,” 2016) and (Why Handoff Scripts Fail, 2022). Note that APA shifts titles into title case in the text even though the reference entry uses sentence case. Do not write “Anonymous” unless the work is genuinely credited to Anonymous.

No date. Use n.d. in both places. But treat an undated web source as a warning: a page that will not say when it was written is a page that does not want to be evaluated.

A source you found inside another source. This is the secondary citation, and it is the most common quiet failure in student research. You read Okonkwo, who quotes a 2009 study by Vega, and Vega’s finding is exactly what you need. The honest move is to go find Vega and read it. If you truly cannot—out of print, untranslated, behind a wall your library cannot open—then cite it as secondary: in text, (Vega, 2009, as cited in Okonkwo, 2021), and put only Okonkwo in your reference list, because Okonkwo is what you actually read.

Generative AI tools. Guidance here is genuinely unsettled and differs by style, institution, and instructor, so the first rule is to read your syllabus. As of APA’s published guidance, a large language model is cited like software, with the company as author: OpenAI. (2024). ChatGPT (Nov 20 version) [Large language model]. https://chat.openai.com, and in text (OpenAI, 2024). MLA takes a different view and declines to treat the tool as an author, recommending instead that you cite the prompt as the title of the source and name the tool as container. Both agree on the substance: describe in your text what you asked and what you did with the output, and keep the transcript. Many instructors additionally require a disclosure statement, which we build in Section 5.

Personal communication. An interview you conducted, an email, a private conversation with a preceptor—APA cites these in text only, because a reader cannot retrieve them: (T. Bell, personal communication, March 2, 2026). Nothing goes in the reference list. MLA does list interviews on the works cited page.

Formatting the page itself

The mechanical layer takes ten minutes once and then never again. APA calls the page References and sets that heading centered and bold; MLA calls it Works Cited, centered and not bold. Either way it starts on a new page. Double-spaced throughout, including within entries. Hanging indent of half an inch. Alphabetical by the first element of each entry, which is usually the surname—and note that alphabetizing is by the entry, so a title-first entry files under its first significant word, ignoring an initial “The.”

Two same-author entries from the same year get lowercase letters: Okonkwo, R. (2021a) and Okonkwo, R. (2021b), assigned by alphabetical order of title, and the letters must appear in the in-text citations too. Do not manually number entries in APA or MLA; numbering belongs to styles like AMA and Vancouver, which many nursing and allied-health journals use and which some of your clinical courses will require. If a course asks for AMA, the logic transfers directly—same four fields, different packaging.

Section 4Plagiarism: The Varieties and the Repairs

The taxonomy, honestly described

Plagiarism is presenting someone else’s words, ideas, structure, or data as your own. Intent does not appear in that definition, which is why “I did not mean to” is a mitigating circumstance in a conduct hearing but not a defense. What follows is the actual range, from deliberate fraud to the honest mistakes that account for most cases instructors see.

Two of these deserve a note about genuine disagreement among scholars. The composition researcher Rebecca Moore Howard named patchwriting and argued it is frequently a developmental stage rather than fraud—the visible trace of a reader working with material slightly beyond her current grasp, clinging to the source’s syntax because she cannot yet restate the idea in her own. Research from the Citation Project supports the picture: student citations cluster in the opening pages of sources, suggesting shallow reading more often than deliberate theft. Many writing programs have responded by treating patchwriting as a teachable skill problem. Many conduct codes still treat it as an offense. Both can be true of the same paragraph, and you should assume your instructor’s policy is the one that governs.

Similarly, some scholars object to the term self-plagiarism on the grounds that you cannot steal from yourself. The objection is fair and the practical rule is unchanged: submitting one piece of work for credit twice misrepresents how much work you did, which is why almost every academic integrity policy names it.

The repairs, worked

Here is a source passage. Everything below is a real revision exercise; cover the right column and try each one before you read the fix.

Source — Okonkwo (2021), p. 44: “Nurses on rotating schedules reported more medication errors than nurses on fixed schedules, but the difference narrowed sharply on units that guaranteed two consecutive days off after a night block.”

The fourth version is the one worth studying. It is not longer or fancier than the patchwriting; it is differently organized, because the writer decided what the finding means before writing the sentence. That is the actual difference between paraphrase and patchwriting, and it happens before you type, not after.

Where honest students get caught

The pattern is boringly consistent. A student takes notes by pasting passages into a document, intending to reword them later. Three days pass. In the draft, some of those pasted lines are now surrounded by the student’s own sentences and no longer look borrowed. Nothing dishonest happened at any single step, and the result is a paragraph that a similarity checker lights up like a runway.

The second pattern is deadline compression. A paper begun at midnight is a paper written with the sources open, and drafting with the source open is how patchwriting happens—your eyes are on their sentence while your fingers produce yours. The mechanical countermeasure appears in the next section, and it is genuinely just: close the tab.

Section 5Systems That Keep You Honest

Capture at the point of reading

The single highest-return habit in academic writing costs about four seconds per note. When you copy anything from a source, do three things immediately: wrap it in quotation marks, add the page or paragraph number, and put the author and year at the end. Every time. Even for a three-word phrase you are “definitely going to reword.”

Better still, use a three-column note format that makes the boundary structural rather than a matter of memory:

Column one can be pasted; columns two and three cannot. That is the point. If you can fill column two without looking at column one, you understood the source. If you cannot, you have found a gap in your reading before it becomes a gap in your paper.

A citation manager—Zotero and Mendeley are free, and your library almost certainly supports one—automates the reference list and, more usefully, holds the PDF next to the entry so you can reopen what you actually read. It will still produce errors: bad metadata in, bad entry out, especially with capitalization and organizational authors. Treat its output as a first draft you proofread against a template, not as finished.

Draft with the source closed

When it is time to write the paragraph, close the article. Write from your notes and your memory. Say what the source showed and why it matters to your argument, in whatever clumsy words arrive. Then—and only then—reopen the source and check two things: is my restatement accurate, and did I accidentally reproduce their phrasing? Fix accuracy problems by revising; fix phrasing collisions by either quoting properly or rewriting the sentence around a different subject.

This one procedural change eliminates most patchwriting, because patchwriting is physically difficult when the original is not on screen. It also improves the prose, since sentences written from understanding are shorter and more direct than sentences written by translation.

The pre-submission audit

Twenty minutes, done once, before every paper that uses sources. Work down the list in order.

Check four has become non-negotiable. Large language models produce reference entries that are formatted flawlessly and describe articles that were never written—plausible authors, plausible journal, plausible DOI, no such paper. One click on the DOI catches it, and a fabricated citation is treated far more seriously than a formatting error, because it is a false claim about what you read.

Disclosing AI use in a way that satisfies a policy

Course policies range from prohibition to encouragement, and they are still moving. Read yours; if it is ambiguous, ask in writing and keep the reply. Where AI use is permitted, a short disclosure note at the end of the paper is usually what is wanted, and specificity is what makes it credible.

Notice what the strong versions have in common: they name the tool, the stage, the specific task, and the boundary—where the tool stopped and you started. That is the same boundary a citation draws around a source.
