What Is a DOI?

A DOI (Digital Object Identifier) is a permanent, unique identifier for a scholarly object — a journal article, book chapter, dataset, preprint, or conference paper. It looks like 10.1038/s41586-020-2649-2, where 10.1038 is the registrant prefix and the rest is the object's unique suffix. DOIs never change, even if the publisher reorganises their website, so they are the most reliable way to link to an academic source.

This differs from a URL, which can break, and from a DOI generator service — some sites let you register a new DOI for your own content, and registries like Zenodo DOI generator are used to mint DOIs for datasets and software you deposit. That's a different task from citation generation. If you already have a DOI and want to cite it in MLA, this page is the tool for you.

What MLA 9 Requires for DOIs

MLA 9th edition has specific rules for how DOIs appear in a Works Cited entry. These are the details our DOI to MLA converter handles automatically:

• Full https URL format — the DOI must be written as https://doi.org/10.xxxx/xxxxx.
• At the very end of the citation — after authors, title, journal, volume, issue, year, and pages.
• Period after the DOI — MLA 9 places a period after the DOI URL at the end of the entry.
• Prefer DOIs over URLs — if the source has a DOI, use it instead of a database URL or permalink.
• No "doi:" prefix — MLA 9 uses the https URL format, not the older "doi:" prefix.
• "et al." for 3+ authors — MLA lists one or two authors in full, and uses "et al." for three or more.

Our tool follows all six rules. The result is a DOI to MLA citation that matches the MLA Handbook exactly.

MLA 9 DOI Citation Format

Here is the standard MLA 9 format for a journal article with a DOI:

Author Last Name, First Name. "Title of Article." Journal Name, vol. X, no. Y, Year, pp. Page–Page. https://doi.org/10.xxxx/xxxxx.

Each element has a rule:

Element	Format
Authors	Last name, First name. Use "et al." for 3+ authors.
Title	In quotation marks, title case, followed by a period inside the quotes.
Journal name	Italicized, title case, followed by a comma.
Volume / Issue	"vol. X, no. Y" followed by a comma.
Year	Four digits, followed by a comma.
Pages	"pp. Page–Page" followed by a period.
DOI	Full https URL, followed by a period.

Example: DOI to MLA 9 Citation

Take the DOI 10.1038/s41586-020-2649-2. Our DOI to MLA citation generator produces:

Harris, Charles R., et al. "Array Programming with NumPy." Nature, vol. 585, no. 7825, 2020, pp. 357–362. https://doi.org/10.1038/s41586-020-2649-2.

Notice how the DOI is a full clickable https URL with a period after it, "et al." is used because the article has many authors, the article title is in quotation marks and title case, and the journal name is italicized while the volume and issue are not.

How to Cite a DOI in MLA 9 — Step by Step

If you need to cite a DOI in MLA manually, here's the process:

1. Start with the author. Use the first author's name in "Last, First" order. If there are two authors, list both separated by "and". If three or more, use the first author's name followed by "et al."
2. Add the article title. In quotation marks, in title case, ending with a period inside the quotes.
3. Add the journal name. Italicized, in title case, followed by a comma.
4. Add the volume and issue. Format as "vol. X, no. Y" with a comma after.
5. Add the year. Four digits, followed by a comma.
6. Add the page range. Format as "pp. 357–362" followed by a period.
7. Add the DOI. Formatted as https://doi.org/10.xxxx/xxxxx, followed by a final period.

The final result is a proper MLA citation with DOI that matches the MLA Handbook. But using our tool means you don't have to remember any of this.

Where to Put the DOI in an MLA Citation

One of the most common questions is where to put the DOI in an MLA citation. In MLA 9, the DOI goes at the very end of the Works Cited entry — after the authors, title, journal name, volume, issue, year, and pages. This is the same position as the URL would occupy in a web source. The DOI takes precedence over any URL when the source has one, which is the standard how to include DOI in MLA citation rule.

How to Format a DOI in MLA

The MLA DOI format is simple:

https://doi.org/10.xxxx/xxxxx

Always use the full https URL, never the "doi:" prefix. Do not capitalize the DOI. Place a period after the URL when it ends the citation. This is the definitive how to format DOI in MLA rule and applies to all source types.

Do You Need to Include a DOI in MLA?

The short answer to do you need to include DOI in MLA is: yes, if the source has one. MLA 9 treats DOIs as the preferred stable identifier for digital sources. If a journal article, ebook, or dataset has a DOI, MLA 9 recommends (and in many academic contexts requires) including it. If there is no DOI, use a URL or database name. If neither is available, end the citation after the page range.

In practice, most journal articles published after 2000 have DOIs. Omitting them in MLA 9 is treated as an incomplete citation by many instructors and journals.

How to Add a DOI to an MLA Citation Manually

If you need to add a DOI to an MLA citation by hand:

1. Write the full MLA citation first, ending with the page range followed by a period.
2. Add a single space after the period.
3. Write the DOI as a full URL: https://doi.org/ followed by the DOI string.
4. End with a period.

That's the complete procedure for how to add DOI to MLA citation. But of course, using our tool means you don't have to remember any of this.

MLA 9 vs MLA 8: DOI Changes

MLA 8 and MLA 9 handle DOIs very similarly, but there are small differences:

Rule	MLA 8	MLA 9
DOI format	Full https URL	Full https URL
Location	At end	At end
Prefix	None	None
Trailing period	Yes	Yes
Authors	"et al." for 3+	"et al." for 3+

The main change from MLA 8 to MLA 9 was clarity and consistency in how contributors, containers, and digital identifiers are handled. If you use a DOI to MLA 9 generator, you're producing the latest format.

MLA In-Text Citations with DOIs

DOIs are not used in in-text citations — only in the Works Cited list. MLA in-text citations use the author's last name and page number (if available):

• Single author: (Harris 358)
• Two authors: (Harris and Millman 358)
• Three or more authors: (Harris et al. 358)
• No page number: (Harris)

If you need to generate matching in-text citations from a DOI, see our DOI in-text citation generator.

DOI to MLA vs DOI to APA 7

Writers often need to convert the same DOI to multiple styles. If you also need a DOI citation APA 7, our DOI to APA 7 converter produces the same reference in APA format. The differences are meaningful:

Element	MLA 9	APA 7
Authors	"et al." for 3+	List up to 20, use &
Year position	After volume/issue	After authors
Title style	Quotation marks, title case	No quotes, sentence case
Journal	Italicized	Italicized
DOI format	Full URL + period	Full URL, no period

Using two separate tools keeps each style correct without manual adjustments.

Common DOI to MLA Mistakes

These are the mistakes we see most often when people convert DOIs to MLA by hand:

1. Using "doi:" as a prefix. MLA 9 uses the full https URL, not the prefix.
2. Forgetting the period after the DOI. MLA 9 ends the citation with a period after the DOI URL.
3. Using a bare DOI string. MLA 9 requires https://doi.org/ before the DOI.
4. Capitalising the DOI. DOIs should be written exactly as registered — usually lowercase.
5. Listing too many authors. MLA 9 uses "et al." for three or more authors.
6. Forgetting the article title in quotes. MLA uses quotation marks around article titles, not italics.
7. Using title case for journal articles. Article titles in MLA are in title case, but this is often confused with sentence case in other styles.
