APA 7 Referencing Explained: In-Text Citations, Reference Lists, and Common Errors

APA 7 is a two-part system. An in-text citation marks the exact point where a source influences your sentence. A reference-list entry tells the reader how to find that source. If the two do not agree, the reader cannot follow the trail, and that is the error markers notice first.

This explainer uses illustrative examples with invented author names, and the reference-list entries are templates rather than real sources. Square brackets mark a placeholder: replace them with a real surname and year in your own work, where the citation would use round brackets.

In-text citations

An in-text citation contains the author and the year. Where it sits depends on how you have written the sentence.

Parenthetical

The whole citation sits in brackets at the end of the sentence:

The relationship between feedback timing and revision quality has been examined across several settings [Nakato, 2021].

Narrative

The author is part of the sentence, so only the year sits in brackets:

Nakato (2021) examined how the timing of feedback affected the quality of revision.

Both forms carry the same information. Choose the one that keeps the sentence readable, and be consistent within a paragraph.

Several sources at once

List them alphabetically as they appear in the reference list, separated by semicolons:

Recent work on supervision has emphasised early agreement on scope [Musoke, 2020; Nakato, 2021].

Direct quotation

A direct quotation needs a page number, or a paragraph number where there are no pages:

"A proposal is an argument for a study, not a description of a subject" [Wasswa, 2022, p. 14].

For a quotation of forty or more words, use a block quotation: indented, without quotation marks, with the citation after the full stop.

Paraphrasing

Paraphrasing means expressing the idea in your own words and your own sentence structure. Changing a few words while keeping the original sentence shape is not paraphrasing, and it is one of the easiest things for a marker to spot.

Paraphrased material still needs a citation, even though there are no quotation marks:

Students who record their search strategy produce more reproducible literature reviews [Wasswa, 2022].

Reference list entries

The reference list is alphabetical by the first author's surname. Every entry ends with a full stop unless it ends with a DOI or URL. The four elements, in order, are author, date, title, and source.

Note the pattern: surname, initials, year in brackets, article title in sentence case, journal name in title case and italics, volume in italics, issue in brackets, page range.

Web page

For a page whose content is likely to change, include a retrieval date. Where the author is the same as the site name, omit the duplicate.

DOI handling

A DOI is a permanent identifier and is the correct thing to give in place of a publisher URL where one exists. Present it as a full link form so the reader can click it. Do not add a retrieved-from statement for a DOI, and do not include a period after it.

Where a work has no DOI, give the URL if the source is stable and free to access. Where the source came from a database that requires a subscription, omit the URL and let the citation point the reader to the database instead.

Common errors

• Mismatch between citation and entry. A name in the text with no entry, or an entry that nothing cites.
• Wrong ordering. Alphabetical by first author surname, not by year and not by order of appearance.
• Titles in title case. Article and book titles use sentence case; journal and book names use title case.
• Missing italics. Journal names and volume numbers are italicised; article titles are not.
• Initials in the text. In-text citations use surnames only, not initials.
• Over-citing one sentence. If three sources support one claim, cite them once, at the end.
• Quotations without page numbers. There is no exception for convenience.
• Citing an abstract as though the full text was read. Cite what you actually read, and if you only saw the abstract, do not attribute detail that was not there.
• Inconsistent dates. The year in the text must be the year in the entry.

A practical workflow

1. Capture the source when you first decide it is worth keeping, with full metadata.
2. Write your note in your own words and mark clearly which sentences are paraphrase and which are quotation.
3. Add the in-text citation as you draft, not afterwards from memory.
4. Generate the reference list from the captured records, then check it against the text.
5. Do a final pass in which you read only the citations and only the entries, and confirm each pair matches.

PassResearch's citation engine keeps the in-text citation and the reference entry tied to the same record, which removes the drift that causes most of the errors above. If you are still assembling the reading, start with finding credible sources so that what you capture is worth citing.

Key takeaways

• In-text citations point; reference entries locate. Both are required for every source.
• Author and year in the text, four elements in the list.
• Quotations need page or paragraph numbers; paraphrases need citations in your own sentence structure.
• A DOI replaces a publisher link and takes no trailing full stop.
• Most marks are lost to mismatches, not to exotic formatting cases.

Confirm the style your department requires before your final submission. Institutional guidelines differ, and where they differ, they win.
