Authorship order and corresponding author: how is authorship decided?

In short

Authorship requires a genuine, accountable contribution to the work (ICMJE's four criteria). Author order follows contribution: the first author contributed most, the last is usually the senior/lead, and the corresponding author manages correspondence and submission. Adding a name just for their title (gift authorship) or excluding a real contributor (ghost authorship) is misconduct. Agree the order and roles in writing before you start writing.

"Where will my name be in the order?" — on multi-author papers this is the most sensitive and dispute-prone question. Authorship isn't a courtesy; it's a matter of accountability: who counts as an author and in what order follows clear rules. Here's how authorship is decided and how to avoid disputes.

Who can be an author?

Under the international ICMJE criteria, authorship requires all four:

  1. A substantial contribution to the design, data or interpretation;
  2. Drafting or critically revising the work;
  3. Approving the version to be published;
  4. Accepting accountability for the whole work.

Merely collecting data, providing funding or general supervision — alone — isn't enough for authorship; those belong in the acknowledgements.

Who is the corresponding author?

The corresponding author manages the submission and correspondence: communication with the editor/reviewers, coordination of revisions and statements, and being the contact for post-publication questions. They needn't be the most senior author — often it's the person who actually wrote the paper. The corresponding author usually coordinates the response-to-reviewers letter too.

What does author order mean?

Position Typical meaning
First author Contributed most; did the work (usually the junior researcher)
Last author Senior/lead (advisor, lab head)
Corresponding author Manages correspondence + submission (independent of order; marked ★)
Middle authors By order of contribution

Caution: this convention varies by field. Some disciplines (e.g. mathematics, economics) list authors alphabetically and don't imply seniority/contribution from order. Learn your target field's norm.

Misconduct: ghost and gift authorship

Avoiding disputes

The most effective way is to discuss up front: decide the author list and order at the start of the work and put it in writing (email suffices); update it as contributions change. Contribution taxonomies like CRediT (conceptualization, methodology, writing, etc.) transparently document who did what and prevent later arguments.

Authorship and order deserve as much seriousness as the paper's scientific content. As you structure your work and prepare it for the right journal, Peerfect's free pre-review engine shows pre-submission gaps — including ethics statements — through an editor's eyes, so both the science and the process are sound.

Frequently Asked Questions

Who can be an author on a paper?

Per ICMJE, authorship requires all four criteria: (1) substantial contribution to the design/data/interpretation, (2) drafting or critically revising the work, (3) approving the version to be published, (4) accepting accountability for the whole work. Collecting data or providing funding alone isn't enough for authorship (those go in the acknowledgements).

Who is the corresponding author?

The author who manages the submission, correspondence with the editor and reviewers, and coordination of revisions and statements. They needn't be the most senior author; often it's the person who actually wrote the paper. Post-publication queries are usually directed to them too.

What do first author and last author mean?

In many fields the first author contributed most (usually the junior researcher who did the work) and the last author is the senior/lead (advisor, lab head). But this convention varies by field; some fields list authors alphabetically.

How do I avoid authorship disputes?

The most effective way is to discuss the author list and order at the start of the work and put it in writing (email is fine). Update the list as contributions change. Contribution taxonomies like CRediT help document transparently who did what.
