First Author vs. Corresponding Author in a Research Paper: How to Decide Authorship, with Examples & Templates

Key Takeaways:

• The first author is usually the person who did the most hands-on work, while the corresponding author manages communication with the journal and readers.
• These 2 roles can be held by the same person or by 2 different people, depending on the field and the lab’s conventions.
• The CRediT taxonomy lists 14 specific contributor roles that make authorship credit more transparent than a simple author list.
• Authorship disputes are best prevented early, using written agreements and the ICMJE criteria, rather than resolved after submission.

Glossary of Key Terms

Term	Definition
First author	The contributor listed first, generally credited with doing most of the research and writing.
Corresponding author	The author responsible for communicating with the journal, editors, and readers before and after publication.
Co-first author	One of 2 or more authors who share equal credit for the first-author position.
Senior author	Often the last-listed author, typically a supervisor or principal investigator who oversaw the study.
CRediT taxonomy	A standardized list of 14 roles used to describe each author’s specific contribution.
ICMJE	The International Committee of Medical Journal Editors, which publishes widely used authorship criteria.
Ghost authorship	When someone who contributed significantly to a paper is left off the author list.
Gift authorship	When someone is listed as an author despite making little or no real contribution.

 

Who Is an Author of a Research Paper?

An author is anyone who made a substantial intellectual contribution to a study and meets all 4 widely used ICMJE criteria: contributing to the work’s design or analysis, drafting or revising it, approving the final version, and agreeing to be accountable for it.

Simply helping with a small task, such as running one assay or proofreading the text, does not automatically qualify someone as an author. Journals distinguish between authors, who take full responsibility for the paper, and contributors, who are acknowledged for narrower help.

The 4 ICMJE Authorship Criteria

• Making a substantial contribution to the conception, design, or acquisition, analysis, or interpretation of data.
• Drafting the manuscript or critically revising it for important intellectual content.
• Approving the final version that will be submitted or published.
• Agreeing to be accountable for all parts of the work, including its accuracy and integrity.

Who Is Usually Not Listed as an Author

• Someone who only provided general supervision without direct intellectual input.
• A person who supplied funding but had no role in the study design, analysis, or writing.
• Technicians or staff who performed routine tasks, such as standard sample processing, without further contribution.
• Anyone who helped with language editing or formatting alone.

Do All Authors Need to Meet Every Criterion?

Yes, most journals require that every listed author satisfy all 4 ICMJE criteria, not just 1 or 2. If someone contributed meaningfully but does not meet every criterion, they are typically listed in the acknowledgments instead.

 

Author vs. Contributor: Key Differences

Not everyone who helps with a study qualifies as an author. This table separates the 2 roles based on the type and depth of contribution involved.

Aspect	Author	Contributor
Definition	Meets all 4 ICMJE criteria for authorship	Provided help but does not meet all 4 ICMJE criteria
Contribution type	Substantial intellectual or creative input to the study	Narrower, often technical or logistical support
Manuscript approval	Reviews and approves the final version before submission	Not required to approve the final manuscript
Accountability	Formally accountable for the accuracy and integrity of the work	Not held accountable for the paper as a whole
Where they are listed	Named in the author byline	Named in the acknowledgments section
Typical examples	Researcher who designed the study, analyzed data, and wrote the draft	Technician who ran routine tests, or an editor who proofread the text

Can a Contributor Later Become an Author?

Yes, if a contributor’s role expands to meet all 4 ICMJE criteria, such as taking on data analysis or manuscript drafting, the author team can add them before final submission with everyone’s agreement.

 

 

 

What Is the Difference Between First Author and Corresponding Author?

The first author typically did the most hands-on research and writing, while the corresponding author manages communication with the journal, reviewers, and readers. One person can hold both roles.

In many fields, the first author position is a marker of primary intellectual and practical contribution. The corresponding author position is more of an administrative and long-term responsibility role. A junior researcher can be first author, while a senior supervisor typically serves as corresponding author.

However, this split is not universal. In some labs, especially smaller ones, the first author is also the corresponding author because they remain reachable and know the project details best. Journals do not require these to be 2 different people.

Example of Author Roles in Practice

Consider a clinical trial with 5 authors. Dr. Reyes, a postdoctoral researcher, designed the experiments, collected data, and wrote the first draft, so she is listed as first author. Dr. Chen is the principal investigator who secured funding and oversees the lab long-term, so she is listed as corresponding author and handles all editor correspondence.

Understanding the CRediT Taxonomy

What Is CRediT?

CRediT, short for Contributor Roles Taxonomy, is a standardized set of 14 roles that describe exactly what each author contributed, rather than relying on author position alone.

Many journals now ask authors to select 1 or more CRediT roles per person during submission. This makes credit more precise, reduces disputes, and helps readers see who did what, beyond guessing from author order.

CRediT Role	What It Covers
Conceptualization	Forming the research ideas, goals, and overall aims of the study.
Data curation	Managing, annotating, and maintaining research data for later reuse.
Formal analysis	Applying statistical, mathematical, or computational techniques to analyze data.
Funding acquisition	Securing the financial support that made the project possible.
Investigation	Conducting the research process, including experiments or data collection.
Methodology	Developing or designing the study’s methodology and models.
Project administration	Coordinating and managing the research activity and its timeline.
Resources	Providing study materials, samples, instrumentation, or other resources.
Software	Programming, developing, or testing software and code used in the study.
Supervision	Overseeing and mentoring the research team and its planning.
Validation	Verifying the overall replication and accuracy of results and findings.
Visualization	Preparing figures, charts, and other visual data presentations.
Writing, original draft	Preparing the initial written draft of the manuscript.
Writing, review and editing	Critically reviewing, commenting on, and revising the draft.

How Do Journals Use CRediT?

Most journals list each author’s CRediT roles in a contributions statement near the end of the paper. This lets readers, reviewers, and hiring committees see specific contributions instead of relying only on author position.

• It reduces confusion over vague terms like “helped with the study.”
• It gives credit to people, such as data managers, who might not otherwise be listed prominently.
• It creates a paper trail if an authorship dispute arises later.
• It is increasingly requested by publishers, including large groups, at submission.

 

How to Write a CRediT Statement/Contributor Statement

A contributor statement, often called a CRediT statement or author contributions section, lists each author’s name alongside the specific roles they performed. It usually appears just before the references or acknowledgments section.

Steps to Write One

• List every author’s full name or initials.
• Match each person to 1 or more CRediT roles, such as conceptualization, investigation, or writing.
• Keep the wording concise, using role names rather than long descriptions.
• Confirm the statement with all authors before submission.

Example 1, Full Names

Maria Reyes: conceptualization, investigation, writing, original draft. Daisy Chen: funding acquisition, supervision, writing, review and editing. Priya Nair: formal analysis, visualization.

Example 2, Initials Only

M.R. and D.C. designed the study; M.R. conducted the experiments; P.N. performed the statistical analysis; D.C. supervised the project and acquired funding; all authors reviewed and approved the final manuscript.

Example 3, Narrative Style

All authors contributed to the study design. M.R. collected the data. P.N. analyzed the results. D.C. supervised the work and secured funding. M.R. wrote the initial draft, and all authors revised it critically and approved the final version.

 

How to Choose the First Author

Key Criteria for First Authorship

First authorship is usually decided by weighing who did the largest share of the actual research and writing work, not simply who has the most seniority.

• Who designed and executed the majority of the experiments or data collection.
• Who performed the core analysis and interpreted the main results.
• Who wrote the first complete draft of the manuscript.
• Who will take primary responsibility if questions or corrections arise later.

 

Tips for Handling Co-First Authors

When 2 or 3 people contributed nearly equally, teams often list co-first authors with a footnote stating they contributed equally. This should be agreed upon and documented before submission, not after a dispute begins.

• Use a clear footnote such as “These authors contributed equally to this work.”
• List co-first authors in an order agreed upon in advance, for example alphabetically or by a coin flip, if contributions are truly equal.
• Document the shared first-author agreement in an email or shared file for future reference.
• Check the target journal’s policy, since some journals limit or format co-first authorship differently.

How to Decide Author Order

Author order communicates a rough hierarchy of contribution and is read differently across fields, so it is worth confirming local conventions early in a project.

Common Author Order Conventions by Field

Field	Typical Order Convention
Biomedical sciences	First author did the most work; last author is the senior supervisor or lab head.
Physics and large collaborations	Often alphabetical, especially for very large author groups on shared instruments.
Economics	Frequently alphabetical, regardless of individual contribution level.
Humanities	Order often reflects the sequence of drafting or the extent of written contribution.
Engineering	Similar to biomedical sciences, with first author as primary contributor and last as principal investigator.

Practical Tips for Ordering Middle Authors

• Rank middle authors roughly by the size of their contribution, from most to least involved.
• Discuss and confirm the full order with all authors before submission, not after.
• Use the CRediT statement to clarify contributions, especially when order alone cannot capture nuance.
• Revisit the order if a co-author’s role changes significantly during revisions.

How to Choose the Corresponding Author

Who Should Serve as Corresponding Author?

The corresponding author should be someone with long-term access to the data, a stable institutional affiliation, and the availability to respond to queries for years after publication.

• A senior researcher, such as the principal investigator, who will remain reachable long-term.
• Someone with full knowledge of the study design, data, and any ethical approvals.
• A person comfortable managing administrative tasks like proofs, forms, and permissions.
• Someone whose institutional email is likely to remain active after publication.

Can the First Author Also Be the Corresponding Author?

Yes, a first author can also serve as corresponding author. This is common when the first author has a stable, long-term position and full command of the project details.

What Are the Duties of a Corresponding Author?

The corresponding author’s core duty is managing all communication about the paper, from initial submission through publication and beyond, on behalf of the whole author team.

• Submitting the manuscript and any required forms through the journal’s system.
• Serving as the main point of contact for editors during peer review.
• Collecting and incorporating feedback from all co-authors during revisions.
• Confirming that every listed author has approved the final submitted version.
• Reviewing and returning galley proofs before final publication.
• Responding to reader questions, comments, or requests for data after publication.
• Handling correction, erratum, or retraction communications if issues arise later.
• Ensuring compliance with the journal’s authorship, ethics, and data-sharing policies.
• Archiving key correspondence and version records for future reference.
• Coordinating responses if the paper is challenged or questioned publicly.

 

Is It Better to Be First Author or Corresponding Author?

Neither role is universally “better”; they carry different types of value, and which one matters more depends on your career stage, field, and goals.

Why First Authorship Often Matters More Early On

• It signals hands-on execution and is heavily weighted in hiring, grants, and PhD or postdoc evaluations.
• In many fields, especially biomedical sciences, it is the most visible marker of who did the core work.
• It is often more important than corresponding authorship when building an early-career track record.

Why Corresponding Authorship Often Matters More Later On

• It signals leadership, oversight, and long-term ownership of a research direction.
• It is commonly expected for senior faculty, principal investigators, or grant holders.
• Some institutions and grant committees specifically look for corresponding authorship as evidence of independent research leadership.

So Which Should You Prioritize?

Early-career researchers generally benefit more from prioritizing first authorship, since it demonstrates direct contribution, while corresponding authorship becomes more valuable once you are managing your own research program.

In practice, many researchers eventually hold both roles on different papers, or even the same paper, so this is less about choosing one over the other permanently and more about what fits a given project and career stage.

 

 

What Is Gift Authorship?

Gift authorship happens when someone is listed as an author despite making little or no real contribution to the study. This person often does not meet any of the 4 ICMJE authorship criteria.

Common Reasons Gift Authorship Happens

• Adding a senior colleague or supervisor out of respect, even without their direct input.
• Listing someone in hopes of a favor, future collaboration, or influence with a journal.
• Including a department head or funder as a courtesy, regardless of actual involvement.

Gift authorship is widely considered a form of research misconduct because it misrepresents who is accountable for the work and can unfairly boost someone’s publication record.

Why Is Gift Authorship a Problem?

Gift authorship misleads readers about who actually did the work and who is responsible for its accuracy, which undermines trust in the paper and in the authorship system as a whole.

What Is Ghost Authorship?

Ghost authorship happens when someone who made a substantial contribution to a paper, such as writing or data analysis, is left off the author list entirely. Their involvement is hidden from readers.

Common Reasons Ghost Authorship Happens

• A medical writer drafts the manuscript but is omitted to make the paper appear fully author-written.
• A company-funded researcher contributes heavily but is excluded to reduce visible conflicts of interest.
• A junior team member’s work is folded into a senior author’s contribution without credit.

Like gift authorship, ghost authorship is considered a serious ethical violation, since it hides real contributions and can conceal financial or organizational influence over the research.

 

Coordinating With Authors After Peer Review

Once reviewer comments arrive, the corresponding author is usually responsible for organizing the revision process among all co-authors, making sure feedback is addressed and everyone approves the final response before resubmission.

Steps for Coordinating Revisions

• Share the full reviewer comments and editor letter with all authors as soon as they arrive.
• Assign specific comments to the authors best positioned to address them, based on their original contribution or expertise.
• Set a clear internal deadline that leaves enough buffer before the journal’s official revision deadline.
• Compile all individual responses into a single, consistent point-by-point reply letter.
• Circulate the revised manuscript and response letter to every author for final review and approval.
• Confirm in writing that all authors agree with the changes before resubmitting.

Common Coordination Challenges

• Authors disagreeing on how to respond to a specific reviewer criticism.
• Delays when a co-author is slow to provide their assigned response or edits.
• Conflicting edits when multiple authors revise the same section independently.
• Difficulty tracking which version of the manuscript is the most current one.

How Long Should Author Coordination Take After Reviews Arrive?

This depends on the journal’s revision deadline, but starting internal coordination within a few days of receiving reviews, and finishing well before the deadline, helps avoid rushed or incomplete responses.

Tips to Keep the Process Smooth

• Use a shared document or version-tracked file so everyone edits the same current draft.
• Keep a running list of unresolved reviewer points until each one is fully addressed.
• Encourage direct, respectful discussion when authors disagree, rather than letting disagreements stall the revision.

 

 

How to Resolve Common Authorship Disputes

Common Types of Authorship Disputes

• Disagreement over who should be listed as first author.
• Gift authorship, where someone is added despite minimal contribution.
• Ghost authorship, where a real contributor is left off the list.
• Disputes over author order among 3 or more middle authors.
• Late requests to add or remove an author after submission.
• Disagreement over who should serve as corresponding author.

Steps to Resolve an Authorship Dispute

1. Revisit the ICMJE authorship criteria, which require substantial contribution, drafting or revising, final approval, and accountability.
2. Ask each disputed contributor to state their specific role, ideally mapped to CRediT categories.
3. Discuss the disagreement directly among the authors before escalating it further.
4. Involve a neutral party, such as a department chair or research integrity officer, if direct discussion fails.
5. Consult the journal’s editorial office, since many have formal authorship dispute procedures.
6. Document the final agreement in writing so the resolution is clear for everyone involved.

Preventing disputes is far easier than resolving them. Many labs now draft a short authorship agreement at the start of a project, listing expected roles and revisiting it if the project’s scope changes.

 

Template Email to Discuss an Authorship Agreement

This template helps a research team confirm author roles, order, and the corresponding author early in a project, reducing the risk of disputes later.

Subject Line

Confirming authorship roles for [project or paper title]

Email Template

Dear all,

As we move forward with [project or paper title], I would like us to agree on authorship roles early, so everyone’s contributions are clearly understood.

Based on our current plan, here is my proposed breakdown:

• First author: [Name], responsible for [main contributions, for example study design, data collection, and drafting].
• Corresponding author: [Name], responsible for journal communication and long-term contact.
• Other authors: [List names and their expected roles, for example analysis, supervision, or funding].

Please review this and let me know if you see it differently, or if your expected contribution changes as the project progresses. I suggest we revisit this agreement if roles shift significantly before submission.

Once everyone agrees, I will save this email as our reference for the author list and contributor statement.

Thank you,
[Your name]

When Should This Email Be Sent?

Ideally, send it at the start of a project, and again before submission to confirm nothing has changed, since roles can shift as the work develops.

 

Template Email for Resolving an Active Authorship Disagreement

This template is meant for situations where a disagreement has already surfaced, such as a dispute over author order, first authorship, or someone being left off the list. The tone stays neutral and focuses on facts and next steps.

Subject Line

Resolving our authorship discussion for [project or paper title]

Email Template

Dear all,

I want to address the disagreement about authorship on [project or paper title] directly, so we can reach a fair resolution before submission.

To keep this clear and fact-based, could each of you briefly summarize your specific contribution, ideally in terms of the CRediT roles, such as conceptualization, investigation, analysis, or writing? This will help us compare contributions objectively rather than relying on assumptions.

Once we have everyone’s input, I propose we:

• Review each person’s stated contribution against the ICMJE authorship criteria.
• Discuss and agree on author order or first-author status based on that comparison.
• Document the final agreement in writing, so it is clear for everyone going forward.

If we cannot reach agreement among ourselves, I suggest we bring in [department chair, research integrity officer, or another neutral party] to help mediate, rather than letting this delay submission further.

I appreciate everyone’s patience while we sort this out fairly.

Thank you,
[Your name]

When Should This Email Be Used?

Send this once a disagreement is already visible, ideally before submission, so the dispute is resolved and documented while it can still be fixed without involving the journal.

 

 

Can AI Be Listed as an Author on a Research Paper?

No, major publishers and organizations such as ICMJE and COPE state that AI tools cannot be listed as authors, because they cannot take responsibility or give consent for the work.

Why AI Tools Cannot Be Authors

• Authorship requires accountability for the work, and an AI tool cannot be held accountable.
• Authors must approve the final manuscript, which requires legal and professional standing an AI tool does not have.
• AI tools cannot hold copyright or agree to conflict-of-interest and ethics declarations.
• Major style guides and publishers, including Nature, Science, and Elsevier, explicitly exclude AI from the author list.

How to Properly Disclose AI Assistance

Instead of authorship, disclose AI use transparently in the methods section or a dedicated acknowledgments statement, describing which tool was used and for what purpose.

• Name the specific AI tool and version used, for example a named language model.
• Describe exactly what the tool helped with, such as language editing, coding assistance, or literature searches.
• State that a human author reviewed and takes responsibility for any AI-assisted content.
• Check the target journal’s specific AI disclosure policy, since requirements vary by publisher.

How to Manage Unresponsive Authors

An unresponsive author, someone who stops replying during drafting, revisions, or final approval, can delay submission or publication. Most journals require confirmation from every listed author before accepting a paper, so this needs a clear, documented process rather than indefinite waiting.

Steps to Handle an Unresponsive Author

• Send a polite reminder through multiple channels, such as email and a phone call, before assuming non-response.
• Set a clear deadline for reply, and state it directly in your message.
• Escalate to a shared supervisor, department contact, or the author’s institution if there is no response after 2 reasonable attempts.
• Document every attempt to reach them, including dates and methods, in case the journal asks for proof later.
• As a last resort, consult the journal’s editorial office, since many have formal policies for handling non-responsive co-authors.

Template 1: Gentle Follow-Up Email

Subject: Following up, [project or paper title]

Hi [Name],

I hope you’re doing well. I wanted to follow up on [project or paper title], since we have not heard back from you regarding [the draft, revisions, or final approval]. Could you please review and reply by [date]? Let me know if you need more time or if anything is unclear.

Thank you,
[Your name]

Template 2: Firmer Follow-Up With Deadline

Subject: Action needed by [date], [project or paper title]

Hi [Name],

We are ready to move forward with [project or paper title] and need your confirmation to proceed. Please review and respond by [specific date], since the journal requires approval from all authors before submission. If we do not hear from you by then, we may need to note your status as unresponsive and proceed accordingly, per journal policy.

Please let us know if there is an issue preventing your response.

Thank you,
[Your name]

Template 3: Escalation to a Supervisor or Institution

Subject: Unable to reach [Author Name] regarding [project or paper title]

Dear [Supervisor or contact name],

I am reaching out because we have been unable to reach [Author Name] regarding [project or paper title], despite multiple attempts on [dates]. As they are a listed co-author, we need their confirmation to proceed with submission. Could you help us get in touch with them, or advise on next steps?

Thank you for your help.

[Your name]

 

 

Can Students Get Published as a Solo Author?

Yes, students can be published as a solo author, especially in fields like humanities, law, or theoretical work, as long as they meet all 4 ICMJE authorship criteria and did not rely on a supervisor’s direct intellectual input.

If a supervisor or collaborator contributed to the study design, analysis, or writing, they generally should be listed as a co-author rather than left out, even if the student did most of the work. Leaving out a real contributor to preserve solo authorship can amount to ghost authorship, which is considered a form of research misconduct.

When Solo Student Authorship Is Common

• Independent projects, such as a thesis chapter turned into a standalone paper.
• Opinion pieces, commentaries, or literature reviews written without direct co-author input.
• Fields where solo-authored work is the norm, such as much of the humanities and law.

When a Supervisor Should Likely Be Listed

• They helped design the study or shaped its core methodology.
• They provided substantial feedback that changed the analysis or argument.
• They secured funding or resources specifically for the project.

 

Do Students Need to Partner With a Senior Researcher to Get Published Faster or in a Better Journal?

No, partnering with a senior researcher is not a requirement for publication, but it can genuinely help. A senior co-author often brings feedback, credibility, and journal familiarity that can speed up review and improve the paper’s chances at a stronger journal.

How a Senior Researcher Can Help

• Providing feedback that strengthens the study design or analysis before submission.
• Suggesting a journal that fits the paper’s topic and rigor level.
• Adding credibility that can make editors and reviewers take the submission seriously.
• Helping navigate revisions if reviewers raise technical or methodological concerns.

When Solo Submission Works Just as Well

• The topic and methods are solid enough to stand on their own merit.
• The student has already published or has strong writing and analytical skills.
• The field or journal does not place heavy weight on author seniority during review.

Journals generally evaluate a paper on its scientific or scholarly merit, not on whether a senior name appears in the author list. However, a partnership should only lead to co-authorship if the senior researcher actually meets the ICMJE criteria, not just to signal prestige, since that would count as gift authorship.

 

Can You Get Published as an Independent Researcher, Not Affiliated With Any University or Research Institute?

Yes, independent researchers can and do get published. Journals evaluate a paper based on the quality, originality, and rigor of the work itself, not on whether the author holds a university or institutional affiliation.

What Independent Researchers Should Expect

• Some submission systems ask for an affiliation field, which can usually be left blank or listed as “independent researcher.”
• A personal or institutional email is often preferred as the corresponding contact, since some journals are cautious about free email addresses.
• Access to expensive resources, such as specialized equipment, lab space, or paid databases, can be a practical barrier, even though it is not an authorship requirement.
• Ethical approvals, such as for human or animal research, may be harder to secure without an affiliated institution’s ethics board, and this can limit certain types of studies.

Fields Where Independent Publishing Is More Common

• Mathematics, computer science, and theoretical fields, where equipment and funding needs are lower.
• Humanities and social sciences, especially essays, commentaries, and literature-based work.
• Citizen science and open-source research communities, particularly in astronomy, ecology, and data-driven fields.

Some independent researchers also partner with an affiliated colleague specifically to access ethics approval, funding, or lab resources, which is a practical workaround rather than a formal authorship requirement.

 

What If an Author Retires or Dies During the Submission Process?

Authorship does not need to change if an author retires or passes away during submission, since authorship is based on the contribution made to the work, not on someone’s current employment or life status.

If an Author Retires

• They remain a listed author, since their contribution to the study does not change after retirement.
• If they were the corresponding author, the team should transfer that role to someone with reliable long-term contact details, since a retired email may become inactive.
• Their approval of the final manuscript, given before retirement, generally still counts, unless major changes are made afterward.

If an Author Passes Away

• They remain listed as an author, since their contribution to the work still stands. However, the journal must be informed immediately.
• Many journals ask the remaining authors to confirm, in writing, that the deceased author would have approved the final version.
• A note is sometimes added to the acknowledgments or a footnote, honoring the author’s passing, though this varies by journal.
• The corresponding author role must be reassigned to another team member who can manage communication going forward.

Journals typically have specific policies for these situations, so it is worth checking the submission guidelines or contacting the editorial office directly if this comes up.

 

 

Frequently Asked Questions

Can 2 people be first authors on the same paper?

Yes, many journals allow co-first authorship when 2 or more people contributed nearly equally. This is usually marked with a footnote stating that the authors contributed equally, and it should be agreed upon before submission.

Who has final say over author order on a manuscript?

There is no single authority; author order is typically negotiated among the co-authors and finalized by mutual agreement, often guided by the PI or seniormost author, before the paper is submitted.

Does the corresponding author have to be the most senior researcher?

No, the corresponding author does not have to be the most senior person. Journals require only that this person can manage communication and remain reachable, though a senior researcher often fills the role in practice.

What happens if a corresponding author changes institutions after publication?

The corresponding author should update their contact details with the journal, since outdated institutional emails can prevent readers or editors from reaching them about corrections, data requests, or follow-up questions.

Can a graduate student be the corresponding author of a paper?

Yes, a graduate student can serve as corresponding author if they have deep knowledge of the study and a reliable, lasting way to be contacted, though many labs prefer a longer-term staff member for this role.

Is the CRediT taxonomy required by all academic journals?

No, CRediT is widely adopted but not universal. Many major publishers require or recommend it, while some smaller or field-specific journals still rely only on a traditional author list and order.

What is the difference between a corresponding author and a co-author?

A co-author is anyone listed on the paper who meets authorship criteria, while the corresponding author is the specific co-author designated to handle communication with the journal, editors, and readers.

How many authors can realistically be listed on one research paper?

There is no fixed cap; single-author papers and papers with hundreds of authors, common in large physics collaborations, both exist. Most standard research papers list somewhere between 2 and 10 authors. Some journals have a restriction on the number of authors for certain article types, like case reports.

Can a patient be a co-author on case report?

Yes, many journals permit a patient to be a co-author on a case report. However, some like BMJ Case Reports do not accept case reports where the patient or relative is the sole author.

How many authors are needed for a systematic review?

The minimum number of authors required is two, because the very design of a systematic review involves having two independent people involved in screening and data extraction. Some journals still accept a systematic review with a solo author, where the other reviewers involved in screening don’t meet all the ICMJE criteria for authorship and hence are listed as contributors instead.

I Got Peer Review Comments With Only Minor Revisions. Do I Still Need Every Author to Approve the Changes?

Yes, even minor revisions should be approved by every listed author, since authorship requires approving the final version of the manuscript, not just the originally submitted draft, under the ICMJE criteria.

Why This Still Matters for Minor Revisions

• Small wording or formatting changes can still shift meaning or emphasis in ways an author may want to review.
• Every author remains accountable for the final published version, so silent approval skips a real responsibility.
• Some journals explicitly require a statement confirming all authors have seen and approved the revised manuscript before resubmission.

A Practical Shortcut for Minor Revisions

• Share the revised manuscript and a short summary of what changed, rather than a full detailed breakdown.
• Ask for a quick reply, such as “approved” or specific concerns, with a short deadline.
• Keep that written confirmation on file in case the journal or a future dispute requires proof of approval.

Skipping this step to save time can create problems later, especially if a correction, dispute, or retraction ever arises and approval records are checked.
