What is group authorship?

Group authorship (also called corporate or collaborative authorship) is the attribution of a research output to a named group — a consortium, study team or collaboration — sometimes alongside individual authors, with specific conventions for the byline and for indexing.

The step most authors miss

Doing CRediT right? Don’t stop at the statement.

A CRediT statement credits you inside one paper. The recognition CRediT was built for happens when those roles are tied to you, persistently. Sign in with your ORCID — free — and claim your CRediT contributions on casrai.org, the home of the standard. They become a verified, portable part of your identity, not a line that disappears into one PDF.

Free: claim your contributions, then export a journal-ready CRediT statement, schema.org structured data, JATS XML, CSV or BibTeX — and preview your public profile. A membership publishes that profile publicly and verifies the journals you serve.

When group authorship is used

Large, multi-site and consortium research often involves too many contributors to list and order conventionally, or is conducted under a collaboration’s collective identity. Group authorship lets the work be credited to a named entity — for example, a clinical-trial group or an international collaboration — either on its own or together with individually named authors. This is common in large clinical trials, genomics consortia and high-energy physics.

Group authorship does not dissolve individual accountability. The ICMJE sets out how to handle it so that responsibility remains traceable to people, not just to a collective name.

Byline conventions

There are two main patterns. In the first, individual authors are listed and the group name is added, for example "Smith J, Patel R, for the EXAMPLE Study Group". In the second, the group itself is the author and the contributing members are listed elsewhere — typically in an appendix or acknowledgement — with those who meet authorship criteria identified as accountable. The ICMJE recommends that when authorship is attributed to a group, the journal specify which group members can take credit and responsibility as authors, and that other members be acknowledged.

Indexing and discoverability

Group authorship has practical consequences for how a paper is found and cited. Bibliographic databases such as PubMed index collective (group) author names as well as individual authors, so a consortium can be searched and credited as an entity, while the named individuals who meet authorship criteria are also indexed. Getting the byline structure right at submission therefore matters for the long-term discoverability and correct attribution of the work.

Recording who did what

For large groups, a structured contribution statement is especially valuable, because a long byline or a collective name reveals little about individual roles. Recording contributions with CRediT lets specific responsibilities — design, analysis, writing, supervision — be attributed to named members even within a large collaboration, supporting both fair credit and accountability. As with all authorship, group members listed as authors should still meet the relevant authorship criteria.

Key facts

At a glance

  • Also called: corporate or collaborative authorship
  • Used for: consortia, trial groups, large multi-site collaborations
  • Pattern A: named authors plus "for the X Group"
  • Pattern B: the group as author, members listed and accountable ones identified
  • Indexing: PubMed indexes collective author names as well as individuals
  • Still applies: members listed as authors should meet authorship criteria

Common questions

FAQ

What is group authorship?+

Group authorship is attributing a publication to a named collaborative group — such as a consortium or study team — sometimes alongside individual authors, using defined byline and indexing conventions.

What is the difference between group and corporate authorship?+

The terms are largely interchangeable: both describe crediting a named collective rather than only individuals. "Corporate authorship" is the older bibliographic term; "group" or "collaborative" authorship is more common in current practice.

How is a study group named in the byline?+

Commonly either as named authors followed by "for the X Study Group", or with the group itself as the author and contributing members listed in an appendix or acknowledgement, with accountable members identified.

How is group authorship indexed?+

Bibliographic databases such as PubMed index the collective (group) author name as well as the named individual authors, so the consortium and the accountable individuals are both discoverable.

Do members of an author group still need to meet authorship criteria?+

Yes. Members who are listed as authors should still meet the relevant authorship criteria; others who contributed but do not qualify should be acknowledged rather than listed as authors.
