DOI in Research Paper: How to Find, Verify, and Use a DOI

A few readers of online research papers may have read something like:

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

Initially, it may appear as a hodgepodge of numbers and letters. However, this tiny piece of code is quite helpful in the academic publishing field. It is known as a DOI (Digital Object Identifier).

The DOI is used to identify a research paper. This provides readers with a way to locate the right paper even if the website changes or the paper is moved to another page on the website.

As a student, researcher, PhD scholar, or a person publishing a research paper for the first time, you might have queries such as:

• What is DOI in research paper?
• Why does a research paper need a DOI?
• How can I find the DOI of a research paper?
• Can I create a DOI myself?
• Does having a DOI mean a journal is Scopus indexed?

Let's learn all with a step-by-step approach and in simple terms.

What Is a DOI in a Research Paper?

A DOI is an identifier for a research publication.

Digital Object Identifier (DOI): It is widely used for journal articles, but can be used for other research materials like datasets, conference papers, reports, and books.

For example:

10.1234/example.2026.001

Upon opening as:

https://doi.org/10.1234/example.2026.001

it takes you to the online page of that research publication.

Simply put, a DOI is like a research paper's "ID card," which is permanent.

A regular web link can be altered. A DOI is intended to stay linked to the identical research work.

What Is DOI in Research Used For?

A DOI is primarily used in research to facilitate identification and retrieval of a research publication.

Suppose you wrote an article now. The journal's website is changed a few years later. The article has jumped from page to page and the original URL no longer works.

This could make it harder for someone to locate your paper.

A DOI is a way to alleviate this issue. The publisher can update the DOI record so that the DOI points to the paper's new location.

Therefore, the DOI will be useful for locating the article even if the website changes.

What Does a DOI Look Like?

The format of a DOI typically begins with the prefix 10. and is followed by a suffix.

For example:

10.1234/abc.2026.001

It can be represented as:

https://doi.org/10.1234/abc.2026.001

The actual format may vary from one publisher to another. There may be some DOI numbers which include journal, article, or other information, or other DOI numbers may appear entirely different.

So, don't worry if two DOI numbers don't look the same. They can still operate the same.

How Does a DOI Work?

It's actually really easy.

A publisher can register a DOI to a research paper from a DOI registration agency once it is published in a journal.

Crossref is one of the popular registration agencies for academic publishing.

The DOI is connected with information about the paper, such as:

• Article title
• Author names
• Journal name
• Publication date
• Volume and issue
• Publisher
• Article webpage

This information is known as metadata.

The DOI system verifies the record when the reader clicks the DOI link and directs him/her to the current online version of the article.

The general procedure is as follows:

Research paper → Journal publishes it → DOI is registered → DOI is connected with article information → Reader uses DOI to find the paper

Who Gives a DOI to a Research Paper?

One of the most frequently asked questions by new researchers.

Usually, the author does not create the DOI.

DOI usually is registered by the journal or publisher. The publisher cooperates with the agency for the DOI registration process and registers the research article.

Therefore, if you have finished your research paper and it's accepted by any journal, then after publishing the accepted research paper, the journal will provide you with a DOI.

The process is generally:

Author → Journal/Publisher → DOI registration → Published article

For papers published in a journal, you should consult the journal website or author guidelines for information on whether or not the journal offers registration of DOIs.

Why Is a DOI Important for Academic Publishing?

This is where a DOI comes into effect, not only for researchers, but also for readers.

1. It Gives Your Paper a Unique Identity

Many research papers can have similar titles or author names. Each registered research object is assigned an identifier called a DOI (Digital Object Identifier).

2. It Makes Your Paper Easier to Find

The DOI will enable readers to access the article without having to conduct a search on the entire website of the journal.

3. It Helps With Citations

If another researcher references your paper, the DOI provides him or her with a dependable mechanism for finding the specific paper.

4. It Supports Citation Tracking

A DOI enables scholarly systems to identify the specific research paper referenced. This can facilitate the linking of reference and research usage.

5. It Can Help With Long-Term Access

If the journal redirects or moves the article on its website, the DOI can be changed to redirect to the new location of the article.

Because of these, it is crucial that a DOI is included as a part of modern academic publishing.

DOI vs URL: What Is the Difference?

A lot of people believe that a DOI and a URL are the same. They are not.

The web address of a page is called a URL.

A DOI is an identifier that is assigned to a research object and is permanent.

For example:

URL:
https://journal.com/article/123

DOI:
10.1234/abc.123

The URL will indicate the current location of the article.

Each article has a DOI, which specifies the article you are discussing.

The URL of the website can be changed, but the DOI should remain linked to the same article.

DOI vs ISSN vs Article ID vs ISBN

There can be multiple numbers in research papers and journals. It can be confusing for new entrants to academic publishing.

For example, a journal can have an ISSN, while each research article published in that journal may have its own DOI.

So, an ISSN and DOI are not the same thing.

What Is DOI Metadata?

The word metadata may sound technical, but the idea is simple.

Metadata is basically information about the research paper.

For example, metadata can include:

• Title of the paper
• Name of the author
• Journal name
• Publication date
• Volume and issue
• Publisher
• Article webpage
• References

What Is DOI Metadata?

While metadata might sound like a technical term, don't worry, it's actually quite simple.

The metadata is information about the research paper.

Some examples of metadata are:

• Title of the paper
• Name of the author
• Journal name
• Publication date
• Volume and issue
• Publisher
• Article webpage
• References

Imagine metadata as the minimal data that would be on the "record" of your research paper.

Correct metadata is important.

For instance, if the author's name is misspelled, it could cause difficulties when searching for a paper or when linking the paper to the author's other publications.

Likewise, an incorrect article URL could lead to readers not being directed to the correct article.

DOI and Crossref: What Is the Connection?

Perhaps you've seen the name Crossref as you search for information on DOI.

One of the larger groups of publishers that assist publishers in registering DOIs for their publications is Crossref.

Information about an article is also submitted as metadata when registering it as an article in a publisher.

This enables the DOI to be linked to the right:

• Article
• Authors
• Journal
• Publication information
• Online location

Therefore, Crossref and DOI are closely related in the academic publishing of journals.

Is There Any Difference Between DOIs and ORCIDs?

No.

DOI vs ORCID: Are They the Same?

The DOI is an identifier for a research publication.

An ORCID is a unique identifier for a researcher.

It can be remembered as follows:

DOI = Which paper is this?

ORCID = Which researcher is this?

The ORCID, for instance, can differentiate between two different researchers with the same name.

A DOI, on the other hand, would identify a specific research paper.

These are beneficial if you are creating a good academic record.

How to Find DOI of a Research Paper

If you are looking about how to find DOI of research paper, fret not. It can be done via several simple methods.

1. Check the Research Paper

Open the PDF file of the paper and view the first page.

The DOI can be displayed close to the:

• Title
• Author details
• Journal information
• Header or footer

2. Check the Journal Website

Navigate to the site that the article came from.

The DOI is often provided in conjunction with the article's publication information.

3. Search Crossref

If a DOI is not provided, you can use a DOI lookup service like Crossref to search for the paper by title or author name.

4. Search Google Scholar

Search for the research paper's exact title.

After locating the right article, examine the article publication details, and search for the DOI.

5. Check Other Research Papers

The paper may have been previously cited by another researcher.

Check the reference list of those papers. That may include the DOI.

How to Check if a DOI Is Correct

Not having a DOI is not a problem. Also, be sure it is the appropriate research paper.

It's easy to check:

Step 1: Copy the DOI.

Step 2: Add https://doi.org in front of it.

Step 3: Click on the link.

Step 4: Check the article title.

Step 5: Check the author names.

Step 6: Check the journal name.

If the DOI takes you to the correct paper, it is likely the right DOI to use.

If it does open another article, avoid using it. Return to the home page of the journal and verify its DOI again.

What If a DOI Does Not Work?

In some cases, clicking on a DOI may lead you to an error page.

Do not make the assumption that the research paper is bogus.

This may be for a number of reasons.

The DOI Was Copied Incorrectly

Failure of a DOI will occur if a single character is missing.

Repeat from the original article or journal site.

The Article Was Recently Published

In some cases, a new paper may not be registered, despite having a DOI.

The Publisher Changed the Website

The DOI record may need to be updated if the journal has changed the location of its website or article.

What Should You Do?

It is best to scrutinize the DOI thoroughly.

Next, look for the article on the journal's web page.

If the DOI fails to work, please contact the journal/publisher.

Does Every Research Paper Have a DOI?

No.

Not all research papers are assigned a DOI.

Some journals register DOIs for their articles, while others do not.

DOIs may also be lacking from older papers, as it was not possible to register or use DOIs when they were published.

Therefore, it is not necessarily the case that a paper without a DOI is not reliable.

If a journal states it has DOIs, however, it's prudent to determine whether the DOI is functional and takes you to the right article.

How to Get Digital Object Identifier for a Research Paper?

If you are an author and interested in obtaining a Digital Object Identifier for your paper, the answer is often as easy as:

It is usually passed on via the journal or the publisher.

Generally, a DOI is not created by the author.

Once your research paper is accepted and published by your publisher, the publisher can submit the article to the DOI Registration Agency for the DOI.

In case a paper is being submitted, please review the website of the journal to determine if it has a publishing system for DOI registration.

The process can be different for other types of research materials, for example, datasets or preprints, where there may be a platform or repository that deals with DOI registration.

Does Having a DOI Mean the Journal Is Scopus Indexed?

No.

This is one of the most crucial aspects that a researcher should know.

A DOI only serves to identify a research publication. It does not establish that the journal is included in Scopus, Web of Science, PubMed, or other databases.

A DOI is not necessarily:

• The journal is Scopus indexed
• The journal is Web of Science indexed
• The paper is peer reviewed
• The journal has an Impact Factor
• The research is high quality

For instance, the DOI could be assigned to a research data set that is not a peer-reviewed journal article.

Therefore, if a journal states that it is Scopus indexed due to the presence of a DOI, do not assume that the journal has a DOI.

Use the official database for a separate check of indexing.

How to Use DOI in a Research Paper Citation

Depending on the style of reference that you are using, you might need to use a DOI in your reference if your paper contains one.

For example:

https://doi.org/10.1234/example.2026.001

References may be formatted differently by various styles of citations.

For instance, the formatting of references is not always consistent from one referencing system to another, such as APA, Vancouver, Harvard, and MLA.

Therefore, if you need to add a citation with a DOI, please verify which referencing style is required by your university, supervisor, or target journal.

The most crucial part is the correct copying of the DOI.

DOI for Journal Articles and Other Research Materials

While we may be familiar with the DOI for a journal article, there are many kinds of research materials that can be assigned a DOI.

These can include:

• Journal articles
• Research datasets
• Conference papers
• Conference proceedings
• Reports
• Books
• Book chapters
• Preprints

Not all research items will have a DOI, as it will depend on the publisher, repository, or platform that publishes the item.

Therefore, DOI should not be interpreted as solely an attribute of journal articles.

Common DOI Mistakes Researchers Should Avoid

If you're new to academic publishing, here are some common pitfalls to avoid.

Mistake 1: Confusing DOI with ISSN

An ISSN will identify a journal. Generally, a DOI is used to identify a particular research object.

Mistake 2: Assuming DOI Means Scopus Indexing

A DOI is not an indicator of indexing.

Mistake 3: Copying the Wrong DOI

Always click on the DOI and make sure it is a link to the right article.

Mistake 4: Typing the DOI Incorrectly

If one letter or number is missing, it will not be usable.

Mistake 5: Assuming Every Paper Has a DOI

For some research papers, there isn't one.

Mistake 6: Thinking DOI Proves Research Quality

A DOI is a unique identifier that identifies a publication. It does not assess the quality of the research.

Common Myths About DOI

DOI Checklist for Researchers

Please spend a minute checking the following before using a DOI in your paper or reference list:

• Is the DOI available?
• Did you copy it correctly?
• Does the DOI open?
• Does it open the correct research paper?
• Are the author's name and article title correct?
• Is the journal information correct?
• Are you using the required citation style?
• Have you confused the DOI with an ISSN or article number?
• If the journal claims to be indexed, have you checked that separately?

Here are a few easy things to do that can save you from citations and publishing issues.

Final Thoughts

A DOI may look like a complicated code when you first see it, but the basic idea is quite simple.

A Digital Object Identifier gives a research publication a unique and persistent identity.

For researchers, it can make papers easier to find, cite, and identify. It can also help keep a connection to a paper even when a journal changes its website.

But remember one important point:

A DOI identifies a research paper; it does not prove that the paper or journal is high quality.

If you are publishing a paper, always check your DOI carefully, make sure it opens the correct article, and don't confuse DOI with ISSN, indexing, peer review, or Impact Factor.

Once you understand these basics, using DOI in research and academic publishing becomes much easier.
