1) General authorship criteria (ICMJE)
Clío Journal adopts ICMJE criteria. A person qualifies as an author only if all the following are met:
• Substantial contributions to the conception or design of the work; or the acquisition, analysis, or interpretation of data.
• Drafting the work or revising it critically for important intellectual content.
• Final approval of the version to be published.
• Public accountability for the integrity of the work, answering for any part of the content.
Those who do not simultaneously meet all four criteria must not be listed as authors.
2) Unacceptable practices
• Honorary, guest, or gift authorship: prohibited.
• Ghost authorship: prohibited.
• Purchase of authorship: prohibited.
• Inclusion of managers, funders, or technical staff who do not meet ICMJE: acknowledge in Acknowledgments, not as authorship.
3) Contribution taxonomy (CRediT)
CRediT statements are mandatory. Common roles (non-exhaustive):
• Conceptualization; Methodology; Software; Validation; Formal analysis; Investigation; Resources; Data curation;
• Writing – original draft; Writing – review & editing; Visualization; Supervision; Project administration; Funding acquisition.
Brief model (for the “Author Contributions” section):
“J.F.V.: Conceptualization, Methodology, Writing–original draft. M.R.: Data curation, Formal analysis, Visualization. L.P.: Supervision, Writing–review & editing, Funding acquisition.”
4) Corresponding author
• Responsible for editorial management, administrative integrity of the submission, and communication with the journal.
• Must ensure: co-authors’ authorization, consistency between author list and CRediT, availability of data/materials, and transparency in funding and conflicts of interest.
5) Authorship order and equal contributions
• Order reflects contribution and is agreed upon by all authors prior to submission.
• Equal contributions (“contributed equally”) are permitted and must be stated explicitly.
• The journal does not mediate authorship disputes; in case of conflict, the process may be suspended until documented institutional resolution is provided.
6) Authorship changes (addition, removal, or reordering)
Any post-submission change requires:
-
A signed request by the corresponding author explaining the reason.
-
Written consent from all authors (including those added/removed).
-
If the article is accepted or published, issuance of a corrigendum or erratum will be considered.
Request template (summary):
• Manuscript title and editorial code.
• Requested change (add/remove/reorder).
• Explicit justification against ICMJE criteria.
• Signed statements of agreement (all authors).
• Date and corresponding author’s signature.
7) Affiliations, identifiers, and transparency
• Indicate current institutional affiliation at the time of the work (up to two).
• ORCID is mandatory for all authors.
• Declare funding sources and conflicts of interest according to the journal’s format.
• Include ethics approvals and consents where applicable.
8) Acknowledgments
Contributions not meeting authorship criteria (technical advice, administrative support, language editing, etc.) should be acknowledged with prior consent of those mentioned.
9) Use of AI tools
• AI tools do not meet authorship criteria and cannot be listed as authors.
• Their use must be disclosed (tool, version, and purpose). Authors remain responsible for accuracy, originality, and rights compliance.
• The use of AI to fabricate data, alter images, or manipulate results is prohibited.
10) Data, materials, and guarantor author
• Appointing a data guarantor author is recommended to ensure traceability and availability in line with the open data policy.
• Any restrictions (contracts, confidentiality, personal data) must be declared and justified.
11) Large collaborations, groups, and consortia
For consortia, authorship may be collective. Provide an appendix listing all members and their CRediT roles. Where a group is listed as author, define how members will be cited in metadata for WoS/Scopus.
12) Deceased or legally incapacitated authors
• A deceased person may be included if authorship criteria were met; add “†” and an explanatory note.
• In cases of legal incapacity, provide documentation and the representative’s consent.
13) Minors and guardianship
Minors shall not be listed as authors. Any contribution should be acknowledged with the consent of legal guardians.
14) Integrity and sanctions
Breaches (gift authorship, concealed contributions, improper AI use, undeclared conflicts of interest) may lead to: manuscript rejection, post-publication retraction, notification to affiliated institutions, and future submission restrictions.
