Citing Sources In APA Format Example | Rules That Stick

An APA citation example pairs an in-text citation with a matching reference entry using author, year, and source details.

APA style can feel picky at first. Once you see the pattern, it turns into a repeatable routine: credit the idea in your sentence, then give the full trail in your reference list.

This page is built for real assignments. You’ll get clear templates, quick checks, and a couple of full samples you can model without guessing which pieces go where.

If you can name the source type, you can format the citation with confidence.

Citing Sources In APA Format Example

APA citations work as a two-part system. The in-text citation tells your reader who said it and when. The reference entry tells your reader where to find it.

If those two parts don’t match, graders can’t verify your source trail. That mismatch can cost points, even when your research is strong.

What Counts As A Source

A source is anything you used to shape your writing: a journal article, a book, a webpage, a report, a video, a dataset, or class materials your instructor posted.

If you didn’t already know the detail and you pulled it from somewhere, treat it like a source and cite it.

Quick Setup Before You Write

  • Decide if you’re paraphrasing (your own wording) or quoting (the author’s exact words).
  • Collect author name(s), year, title, and where you found it (journal, site, publisher, URL, DOI).
  • Start a reference list early, then add entries as you go.

What APA Citations Include

Most APA references are built from the same building blocks. Learn the blocks, and you can cite almost anything.

Source Type Reference List Template In-Text Citation Template
Journal Article Author, A. A. (Year). Title of article. Journal Title, volume(issue), pages. DOI/URL (Author, Year) or Author (Year)
Book Author, A. A. (Year). Title of book. Publisher. (Author, Year)
Chapter In Edited Book Author, A. A. (Year). Title of chapter. In E. E. Editor (Ed.), Book title (pp. xx–xx). Publisher. (Author, Year)
Webpage Author, A. A. (Year, Month Day). Title of page. Site Name. URL (Author, Year) or (Author, Year, para. #)
Report Organization Name. (Year). Title of report. Publisher/Organization. URL (Organization Name, Year)
Online Video Uploader, U. U. (Year, Month Day). Title of video [Video]. Site Name. URL (Uploader, Year, time stamp)
Dataset Author/Org. (Year). Title of dataset (Version) [Data set]. Publisher. URL (Author/Org., Year)
Conference Paper Author, A. A. (Year, Month). Title of paper [Conference presentation]. Conference Name, Location. URL (Author, Year)
Thesis Or Dissertation Author, A. A. (Year). Title (Publication No.) [Master’s thesis/Doctoral dissertation, University]. Database/Repository. URL (Author, Year)

When you need a model for a specific source type, the official APA Style reference examples page is a steady checkpoint.

In-Text Citations That Read Smoothly

In-text citations can sit at the end of a sentence, or they can be woven into the sentence itself. Both work. Pick the one that keeps your writing flowing.

Use author and year for most citations. Page numbers show up when you quote, or when your instructor asks for page-based proof for a print source.

Paraphrase Vs Quote

Paraphrasing is common in student writing. You restate the idea in your own words, then cite author and year.

Quoting means copying the author’s wording. Quotes need author, year, and a locator such as a page number (p. 12) or paragraph number (para. 4) for a webpage.

Author Patterns You’ll Use All The Time

For one author, use the surname and year: (Nguyen, 2023). For two authors, use both surnames each time: (Nguyen & Patel, 2023).

For three or more authors, use the first author’s surname plus “et al.” from the first citation onward: (Nguyen et al., 2023).

Group Author And No Author

If a group wrote the work, use the group name: (World Health Organization, 2022). If there’s no listed author, move the title into the author spot.

For a title in the citation, use quotation marks for an article or page title, and italics for a standalone work like a report or book.

Time Stamps For Audio And Video

When you cite a spoken moment, add a time stamp so a reader can jump to it: (Uploader, 2024, 1:18–1:42).

Placement And Punctuation

In most cases, the period goes after the parenthetical citation: (Nguyen, 2023). If the author is part of your sentence, place the year right after the name: Nguyen (2023) found that…

When you cite more than one source in the same parentheses, list them in alphabetical order and separate them with semicolons. This keeps the citation tidy and easy to scan.

If you want a quick rule check from the source, the APA in-text citation principles page lays out the patterns in plain terms.

Reference List Entries That Match Your Source

Your reference list sits at the end of the paper. Each entry starts with the same author and year you used in your in-text citation, so the reader can match them fast.

Most entries follow this order: author, date, title, and source. The “source” part changes based on what you used, like a journal name, a publisher, or a website.

Journal Articles

For a journal article, italicize the journal title and the volume number. The issue number goes in parentheses right after the volume and is not italicized.

Article titles use sentence case. That means you capitalize the first word, the first word after a colon, and proper nouns.

Books, Chapters, And Reports

For a whole book, italicize the book title, then list the publisher. In APA 7, you don’t add the publisher’s location.

For a chapter in an edited book, cite the chapter author as the author of the entry, then list the editor and the book details after the chapter title.

Webpages And Videos

For webpages, watch the date. Use the most specific date shown on the page. If no date is listed, use (n.d.).

For videos, include the uploader, date, title, a bracketed description like [Video], the site name, and the URL.

Formatting Details That Change The Grade

APA style is not only about what you cite. It’s also about how the reference list is formatted on the page.

These details are easy to miss during drafting, so build them into your final edit pass.

Hanging Indent, Spacing, And Order

Use double spacing for the whole reference list unless your instructor asks for something else. Apply a hanging indent so the first line starts at the margin and the next lines are indented.

Sort entries alphabetically by the first author’s surname. If an author has multiple works, sort those by year, oldest to newest.

Italics And Title Rules

In APA references, titles of standalone works are italicized, like books and reports. Titles of parts of a larger whole are not italicized, like journal articles and book chapters.

Use sentence case for titles in the reference list. Journal titles keep their normal capitalization.

URLs And DOIs

Write DOIs as URLs that start with https://doi.org/. For regular URLs, copy them carefully so they work when clicked.

Most sources don’t need “Retrieved from.” Retrieval dates are used when content is built to change over time, like a wiki page.

A Full Sample You Can Model

Here’s one complete sample built from a common student source: a webpage written by a group author with no date shown.

First, place the credit inside your sentence. Then, add the matching reference entry in your list.

Sample In-Text Citation

Writers lose points when their citations and reference entries don’t match (American Psychological Association, n.d.).

Sample Reference Entry

American Psychological Association. (n.d.). Reference examples. APA Style. URL

Swap in your source details here.

That “Site Name” line is where many students slip. If the author and the site are the same group, drop the site name. If the site is different from the author, keep it.

APA Format Citation Examples For Fast Checking

This section is a quick pattern matcher. Use it when you have a source in front of you and you want to format it without second-guessing.

Webpage With No Individual Author

If the page is credited to an organization, treat that organization as the author.

In text: (National Park Service, 2022). In references: National Park Service. (2022, May 4). Title of page. URL

Article Found In A Library Database

If a journal article has a DOI, use it. If it doesn’t, you usually don’t add the database name unless the work is hard to retrieve outside that database.

Class Notes And Slides

Class slides and lecture notes are often treated as personal communications, which means they may be cited in text but not listed in the references, depending on your course rules.

Common Errors And Clean Fixes

Most citation problems are small. They come from mixing templates, dropping a date, or formatting a title like MLA instead of APA.

Use this table as a final sweep before you submit.

Slip What It Causes Clean Fix
In-text name doesn’t match reference Reader can’t trace the source trail Make author and year identical in both places
Using a website title as the author Wrong author credit Use the person or organization shown as the author
Missing date on a webpage Weakens time context Use the page date or (n.d.) if none is listed
Title in the wrong case Entry looks inconsistent Use sentence case for titles in the reference list
DOI pasted as a long database link Broken link or messy entry Use the https://doi.org/ format when a DOI exists
No page or paragraph for a quote Quote can’t be located Add a page number, or a paragraph number online
Extra punctuation after a URL Link may not work End the entry with the URL and nothing after it
Hanging indent missing Reference list is hard to scan Apply a hanging indent to each entry

Quick Proofread Checklist Before You Submit

Give your paper one last citation pass after you finish writing. It’s faster than you think, and it catches small slips that cost points in class.

  • Each in-text citation has a matching reference entry, unless it’s personal communication.
  • Each reference entry is cited in the paper.
  • Author spellings match across text and references.
  • Years match across text and references.
  • Titles use sentence case in the reference list.
  • Journal titles and volume numbers are italicized.
  • URLs and DOIs work when you click them.
  • Hanging indent and spacing are consistent.

Practice matters. When you draft a paragraph, then build the reference entry right away, citing sources in apa format example turns into muscle memory.

After a second pass, citing sources in apa format example feels like a simple pattern match, not a guessing game.
