How to APA Reference Any Source Correctly
Updated May 2026 | APA 7th Edition
APA referencing follows the same core structure for every source: Author. (Year). Title. Source. The specific elements in each position vary by source type. To APA reference any source correctly: identify the source type, gather author/date/title/source information, apply the APA 7th edition format for that type, and verify your formatting against the examples in this guide.
The Universal APA Reference Formula
Regardless of source type, every APA reference has four core elements in this order:
Step-by-Step: How to Create an APA Reference
- Identify your source type — Is it a website, book, journal article, PDF, video, or other? The type determines which APA template you follow.
- Find the author — Look for an author name. If no individual author, look for an organization name. If none, the title will go first.
- Find the date — For most sources, the year is sufficient. For web pages and news articles, use year, month, and day when available.
- Record the title — For containers (books, journals, websites): italicize. For articles, chapters, or specific pages: do not italicize.
- Record the source details — Publisher (for books), journal name + volume + issue + pages + DOI (for articles), or website name + URL (for web).
- Format using our free APA reference generator — paste in your details for an instantly formatted APA citation.
APA Reference Formats: Decision Table

| Journal Article | Volume, issue, pages in source | Italicize journal name + volume; use DOI |
| Website | URL in source position | Italicize page title; no access date |
| PDF Report | [PDF] label after title | Use organization as author if no individual |
| YouTube | [Video] label after title | Include full date (year, month, day) |
| Book Chapter | Editor listed with (Ed.) | Chapter author first, book editor after |
| Podcast | [Audio podcast episode] | Include episode number if available |
Frequently Asked Questions
How do I start an APA reference?
Every APA reference starts with the author element — typically the author's last name followed by their first initial: Smith, J. A. If there is no author, the title moves to the first position. If the author is an organization, write the full organization name. After the author, write the publication year in parentheses: (2024). This author-date opening is the foundation of every APA reference.
What is the difference between a citation and a reference in APA?
In APA, "citation" usually refers to the in-text citation — the brief (Author, Year) notation within your paper. "Reference" refers to the full bibliographic entry in the reference list at the end of your paper. Every citation in the text corresponds to a reference in the list, and every reference must have at least one in-text citation.
How do I reference a source I cannot find a date for?
If a source genuinely has no publication date, use (n.d.) — no date — in parentheses. Example reference: Smith, J. (n.d.). Title of the page. Website Name. URL. In-text: (Smith, n.d.). Before using n.d., thoroughly check the page: look at the page header, footer, source code meta tags, and any "last updated" notes. Many pages have dates that are not immediately visible.
Can I use APA reference for all academic writing?
APA reference format is appropriate for academic writing in psychology, social sciences, education, business, nursing, communications, and related fields. Other disciplines use different citation styles: humanities typically use MLA or Chicago, history and social science often use Chicago, and medical sciences use Vancouver/NLM. Always confirm which style your institution or journal requires before applying APA.
How do I reference a database article in APA?
For database articles (JSTOR, EBSCOhost, ProQuest, etc.), APA 7th edition does NOT require you to name the database. If the article has a DOI, use it as your URL: https://doi.org/xxx. If no DOI, use the journal's official homepage URL. Only use the database URL as a last resort if no other URL exists. The database is a delivery mechanism, not the publisher.
How do I reference a book I found online (e-book) in APA?
For an e-book with a DOI: Author, A. A. (Year). Title. Publisher. https://doi.org/xxx. For an e-book from an online library (Kindle, Project Gutenberg): Author, A. A. (Year). Title. Publisher. URL or platform. If the book is available in both print and digital, you do not need to specify the format — just include the DOI or URL if available. No "e-book edition" notation is needed in APA 7th.
Do I need to reference everything I read for a paper?
No — you only reference sources you actually cite in your paper. You may read 30 sources while researching but only cite 10 in the text. Only those 10 go in the reference list. APA uses a "References" page (not a bibliography), which includes only cited sources. If your assignment requires a bibliography (all sources consulted), your instructor will specify this.
What is a hanging indent and why does APA use it?
A hanging indent in APA means that the first line of each reference starts at the left margin, and all subsequent lines of the same entry are indented 0.5 inches. This formatting makes it easy to quickly scan the reference list by author name. In Microsoft Word: select all references, then Format → Paragraph → Special → Hanging → 0.5". In Google Docs: Format → Align & indent → Indentation options → Special indent: Hanging.
