IJCI considers only original content, articles that have not been previously published. IJCI will consider articles based on previously made public content only on a preprint server, institutional repository, or thesis.
Manuscripts submitted to IJCI must not be submitted elsewhere while under consideration and must be withdrawn before being submitted elsewhere. Authors whose articles are found to have been simultaneously submitted elsewhere may incur sanctions.
If authors have used their own previously published work, or work that is currently under review, as the basis for a submitted manuscript, they must cite the previous articles and indicate how their submitted manuscript differs from their previous work. Reuse of the authors’ own words outside the Methods should be attributed or quoted in the text. Reusing the authors’ figures or substantial amounts of wording may require permission from the copyright holder, and the authors are responsible for obtaining this.
IJCI will consider extended versions of articles published at conferences provided this is declared in the cover letter, the previous version is cited and discussed, there is significant new content, and any necessary permissions are obtained.
Redundant publication, the inappropriate division of study outcomes into more than one article may result in rejection or a request to merge submitted manuscripts and correct published articles. Duplicate publication of the same, or a very similar, article may result in the retraction of the later article, and the authors may incur sanctions.
