TL;DR

• Creative Commons licenses let authors control how others use their work.

• Six main license types exist, from fully open to nearly all rights reserved.

• Most open access journals require a CC BY license on submission.

• Choosing the wrong license can limit reuse or conflict with journal policies.

• Understanding licenses before you submit saves time and avoids rejections.

You finished your research paper. You are ready to submit. Then the journal asks you to choose a Creative Commons license, and you have no idea what that means or which one to pick. This is one of the most common points of confusion for first-time academic authors, and it matters more than most people realise.

The license you attach to your paper determines who can read it, share it, translate it, build on it, or use it commercially. Get it wrong and you may accidentally give away rights you wanted to keep, or restrict your work in ways that conflict with your funder's requirements or the journal's own policies.

This post explains what a Creative Commons license is in publishing, how the different types work, and how to choose the right one before you submit your paper.

What Is a Creative Commons License in Publishing?

A Creative Commons (CC) license is a standardised legal tool that lets authors grant the public permission to use their work under specific conditions, without requiring anyone to ask permission each time. In academic publishing, CC licenses are most commonly attached to open access articles so that readers, researchers, and institutions know exactly what they are allowed to do with the paper.

Creative Commons is a nonprofit organisation that created these licenses in 2001. The licenses are internationally recognised and legally enforceable. They sit between full copyright, where all rights are reserved by the author, and the public domain, where no rights are reserved at all. When you publish a paper under a CC license, you keep your copyright but give others a clear set of permissions.

For student researchers, this matters because many journals, particularly open access journals indexed in the Directory of Open Access Journals (DOAJ), require authors to apply a CC license as a condition of publication. If you do not understand what you are agreeing to, you may sign away more than you intended.

How the Six Creative Commons Licenses Work

There are six Creative Commons licenses. Each one combines a set of conditions that either allow or restrict what others can do with your work. The conditions are: Attribution (BY), ShareAlike (SA), NonCommercial (NC), and NoDerivatives (ND). Understanding these four building blocks makes every license readable.

Here are the six licenses in order from most open to most restrictive:

1. CC BY (Attribution): Others can share, adapt, and use your work commercially, as long as they credit you. This is the most permissive license and the one most commonly required by open access mandates.

2. CC BY-SA (Attribution-ShareAlike): Others can share and adapt your work, including for commercial purposes, but they must license their new version under the same terms.

3. CC BY-NC (Attribution-NonCommercial): Others can share and adapt your work but not for commercial purposes. They must credit you.

4. CC BY-NC-SA (Attribution-NonCommercial-ShareAlike): Others can share and adapt your work for non-commercial purposes only, and they must use the same license.

5. CC BY-ND (Attribution-NoDerivatives): Others can share your work in its original form, including commercially, but they cannot create adaptations or modified versions.

6. CC BY-NC-ND (Attribution-NonCommercial-NoDerivatives): This is the most restrictive CC license. Others can download and share your work for non-commercial purposes only, without any modifications, and must credit you.

According to Creative Commons, CC BY is the license recommended by the Budapest Open Access Initiative and required by major research funders including the Wellcome Trust and the Bill and Melinda Gates Foundation for any research they fund.

What Is a Creative Commons License in Publishing and Why Do Journals Care?

Journals care about Creative Commons licenses because they define the legal framework for distributing your paper. Open access publishing, where articles are freely available to anyone online, only works if the license attached to the article makes that distribution legal. Without a CC license, a journal cannot legally post your paper publicly, even if you want them to.

PLOS ONE, one of the largest peer-reviewed open access journals in the world, requires all submitted articles to be published under a CC BY license. This is stated explicitly in their publication policies. PLOS ONE's reasoning is that CC BY maximises the reach and reuse of published research. Similarly, journals published by MDPI, which operates over 400 peer-reviewed open access journals, default to CC BY for most of their publications.

If you are submitting to a subscription-based journal that offers an open access option, sometimes called a hybrid journal, you will typically be asked to choose a CC license only if you opt into open access. If you do not opt in, your paper sits behind a paywall and standard copyright terms apply.

If you want to understand how open access publishing works more broadly before choosing a license, the post on open access publishing and whether you should care covers the full landscape in plain language.

If you are a student researcher trying to navigate journal requirements and submission decisions, joining the Publication Compass waitlist gives you early access to a platform built to help you match your paper to the right journal and understand exactly what each journal requires before you submit.

Which Creative Commons License Should You Choose?

The right license depends on three things: what your funder requires, what the journal accepts, and how you want your work to be used. Start with the first two, because they are non-negotiable. Your personal preference only applies in the space those constraints leave open.

Here is a simple decision process:

1. Check whether your research was funded by an organisation with an open access mandate. If yes, that mandate will specify which license is required. Most major funders require CC BY.

2. Check the journal's author guidelines. The guidelines will state which CC licenses they accept. Some journals only accept CC BY. Others allow CC BY-NC or CC BY-NC-ND.

3. If neither your funder nor the journal specifies, consider how you want your work used. If you want maximum reach and reuse, choose CC BY. If you want to prevent commercial use without your involvement, choose CC BY-NC.

For most high school and undergraduate student researchers who are not operating under a funder mandate, the choice usually comes down to what the journal requires. Many student-facing journals, including the Journal of Student Research and the American Journal of Undergraduate Research, publish under open access terms and will specify their license requirements in their submission guidelines.

One important note: once you publish under a CC license, you cannot revoke it. According to Creative Commons' own FAQ, if someone has already received a copy of your work under a CC license, that license remains valid for them even if you later change your mind. Choose carefully before you submit.

What Is a Creative Commons License in Publishing Versus Full Copyright?

Full copyright means all rights are reserved by default. No one can reproduce, share, or adapt your work without asking you directly. This is the default legal position for any original work in most countries, including the United States, under the Berne Convention. You do not have to do anything to have copyright. It exists automatically when you create an original work.

A Creative Commons license does not replace your copyright. It builds on it. You still own the copyright. What you are doing is granting a pre-approved, standardised set of permissions so that others do not need to contact you every time they want to share or cite your paper.

This distinction matters because some students worry that applying a CC license means giving up ownership of their work. That is not what happens. You remain the author. Your name stays on the paper. The license only governs how others can use it, not who created it.

For context on what happens to your rights and your paper after it is accepted, the post on what happens after your paper is accepted walks through the post-acceptance process step by step, including copyright transfer agreements, which are separate from CC licenses.

It is also worth understanding how peer review fits into this process, since your paper will go through review before any license question becomes final. The post on what peer review is and what happens to your paper explains that process clearly.

Common Mistakes Student Researchers Make With CC Licenses

Most licensing mistakes happen because students do not read the journal's author guidelines carefully enough before submitting. Here are the most common errors and how to avoid them.

The first mistake is assuming the journal will choose the license for you. Some journals do apply a default license, but many ask you to select one during submission. If you skip this step or leave it blank, your submission may be returned or delayed.

The second mistake is choosing the most restrictive license without checking funder requirements. If your research was supported by a grant or a school programme with an open access policy, that policy may require CC BY. Submitting under CC BY-NC-ND when CC BY is required can result in a compliance problem after publication.

The third mistake is confusing a CC license with a conflict of interest statement. These are two different things. A conflict of interest statement discloses relationships that might bias your research. A CC license governs how your published paper can be used. The post on conflict of interest statements in academic publishing covers that separate requirement in full.

Publication Compass helps researchers understand journal-specific requirements, including licensing policies, before they submit. It is a software platform, not a consulting service, and it is built to make this kind of preparation faster and more accurate for student authors.

FAQ

Do I need a Creative Commons license if I am publishing in a subscription journal?

Not necessarily. Subscription journals keep articles behind a paywall and typically use standard copyright terms. You only need to choose a Creative Commons license if the journal offers or requires open access publication. Check the journal's author guidelines to confirm their policy before you submit.

Can I use a CC license on a paper I co-authored with a teacher or professor?

Yes, but all co-authors must agree to the license choice before it is applied. A CC license is a legal grant of permissions on behalf of all copyright holders. If one co-author objects to a specific license type, you will need to negotiate before submission. Discuss this with your co-authors early in the process.

What happens if someone violates my Creative Commons license?

A CC license is a legal document. If someone uses your work in a way that violates the license conditions, for example using a CC BY-NC paper commercially without permission, they are in breach of copyright law. You can contact them directly or seek legal remedy. Creative Commons provides guidance on enforcement on their website.

Is CC BY the same as putting my paper in the public domain?

No. CC BY still requires attribution. Anyone who uses your work must credit you as the author. The public domain (CC0) removes all restrictions, including the requirement to give credit. Most journals and funders use CC BY rather than CC0 precisely because it preserves the author's right to be acknowledged.

Can I post a preprint before submitting and then apply a different license to the published version?

Yes, in most cases. Preprints and published versions are treated as separate items. You can post a preprint under one license and publish the final version under the license your journal requires. The post on what a preprint is and whether you should upload before submitting explains how preprint policies interact with journal submission.

Choosing the Right License Is Part of Submitting Well

Understanding what a Creative Commons license is in publishing is not just a technicality. It is part of submitting your paper correctly the first time. The license you choose affects how your work reaches other researchers, whether it complies with funder requirements, and how your paper is indexed and shared after publication. Taking ten minutes to read the journal's licensing policy before you submit is time well spent.
