Publishing your research as open access makes your work more discoverable, reusable, and impactful. But the biggest challenge researchers face is choosing the right open access license. Each license defines what others can—and cannot—do with your work. Choosing the wrong one may limit your research’s reach or unintentionally allow commercial or derivative use you never intended.
This guide explains what an open access license is, how the major Creative Commons (CC) licenses differ, and how to choose the one that best aligns with your goals as an author.
What Is an Open Access License?
An open access license is a legal framework that determines how the public can use, share, remix, adapt, or commercialize your research. It ensures your rights as an author while giving others clarity on what’s permissible.
The most common open access licenses used in academic publishing are Creative Commons (CC) licenses. Journals, preprint servers, universities, and open repositories rely on these licenses to standardize permissions globally.
Open access licenses matter because they determine:
- How widely your work is shared
- Whether commercial entities can use it
- Whether others can modify it
- Whether authors must cite you (they must in all CC licenses)
- Whether derivative versions can exist
Choosing a license thoughtfully protects your intellectual contribution while maximizing your research impact.
Why Your Choice of Open Access License Matters
Many researchers select a license without fully understanding the implications. Yet this decision affects:
1. Research Visibility and Reach
More permissive licenses (e.g., CC BY) increase sharing, citations, and reuse.
More restrictive licenses reduce misuse but may also limit impact.
2. How Others Use Your Work
Your license determines whether your paper can be:
- Translated
- Adapted
- Included in textbooks
- Used in training datasets
- Integrated into commercial tools
3. Compliance with Journal and Funder Requirements
Some funders require specific licenses.
For example:
- Wellcome Trust → CC BY
- NIH → Encourages broad reuse
- European Horizon 2020 → CC BY
4. Long-term academic and societal influence
Choosing a restrictive license may prevent your work from contributing to:
- Education
- Policy development
- Industry innovation
- Community engagement
In essence, your license determines how far your research travels.
Overview of Creative Commons Licenses
All CC licenses require attribution (BY).
The variations come from three additional rules:
- NC — Non-commercial use only
- ND — No derivatives or adaptations
- SA — Share-alike (derivatives must use the same license)
Below is a breakdown of each license used in academic publishing.
1. CC BY (Attribution Only) — Most Open & Research-Friendly
What it allows:
- Sharing, remixing, adapting, and commercial use
- As long as proper attribution is given
Best for:
- Maximizing visibility and citations
- Complying with major funder policies
- Open educational resources
- AI/ML dataset contributions
- Policy and public health research
Many journals (e.g., PLOS, Springer Open) prefer or require this license.
2. CC BY-SA (Attribution + Share Alike)
What it allows:
- Sharing and adaptation
- Commercial use
- Derivatives must use the same license
Best for:
- Open-source style academic communities
- Collaborative research projects
- Researchers wanting to maintain openness downstream
Not ideal if you want more control over how derivatives are licensed.
3. CC BY-ND (Attribution + No Derivatives)
What it allows:
- Sharing
- Commercial use
What it forbids:
- Adaptations, remixes, translations, abridgements
Best for:
- Authors wanting strong protection
- Policy briefs
- Opinion papers
- Sensitive research
Note: Many open access journals discourage ND because it restricts scholarly reuse.
4. CC BY-NC (Attribution + Non-Commercial)
What it allows:
- Sharing
- Adaptations (non-commercial only)
What it forbids:
- Commercial reuse
Best for:
- Educational content
- Research with community co-creation
- Sensitive data that shouldn’t be commercialized
Common in humanities, but less accepted in STEM fields.
5. CC BY-NC-SA (Non-Commercial + Share Alike)
A blend of NC and SA rules.
Best for:
- Projects aiming to protect community-generated knowledge
- Educational research wanting downstream openness but no commercial use
6. CC BY-NC-ND (Most Restrictive)
Allows:
- Sharing only
Forbids:
- Commercial use
- Adaptations
Best for:
- High-risk topics
- Sensitive cultural or indigenous knowledge
- Clinical or policy-sensitive findings
This license is allowed but not considered “fully open access” by many publishers.
How to Choose the Right Open Access License
Selecting the best license depends on your goals, discipline norms, and the expectations of your funders or journal.
Here’s how to decide:
1. Determine Your Priority: Visibility vs. Control
If your goal is:
✔ maximum exposure, citations, and reuse
→ Choose CC BY
When your requirement is:
✔ controlled use, no modifications
→ Choose CC BY-ND
If you need strict compliance:
✔ restrict commercial exploitation
→ Choose CC BY-NC or CC BY-NC-ND
2. Check Journal Requirements Before Submitting
Many journals specify mandatory licenses.
For example:
- PLoS → CC BY
- BMC → CC BY
- Taylor & Francis Open → CC BY or CC BY-NC-ND (depending on article type)
- Elsevier Open → CC BY, CC BY-NC-ND, CC BY-NC-SA (varies by journal)
Not complying with licensing rules may delay acceptance.
3. Check Funder Policies
If you have research funding:
- Review their open access mandate
- Many funders explicitly require CC BY
- Some only accept open access if licensing is permissive
Always match funder policy first.
4. Consider Ethical and Community Implications
For sensitive research (e.g., indigenous knowledge, community-based participatory research):
- A restrictive license such as CC BY-NC-ND may protect misuse
- Some communities want no commercial use or modification
Always respect ethical obligations over openness.
5. Think About Long-Term Impact
Ask yourself:
- Do I want educators to reuse this?
- Do I want my findings to become part of AI/ML datasets?
- Do I want translations or adaptations?
- Am I okay with commercial entities using it?
Your answers point to the appropriate license.
Example Scenarios
Scenario 1: Maximizing global reach
→ Choose CC BY
Scenario 2: Preventing corporate use
→ Choose CC BY-NC
Scenario 3: Preventing any edits or changes
→ Choose CC BY-ND
Scenario 4: Keeping all adaptations equally open
→ Choose CC BY-SA
Scenario 5: Protecting sensitive findings
→ Choose CC BY-NC-ND
