Cochrane’s editorial and publishing policies can now be found on the Cochrane Library Editorial policies page. Cochrane authors and editorial teams should refer to the Cochrane Library as the primary source of information on this policy. For editorial guidance on policies the EPPR remains the primary location.
The co-publication of Cochrane Reviews in other journals is permitted in certain circumstances to support the dissemination of the findings of Cochrane Reviews. In general, the journal for the co-publication is likely to be a specialist publication (and therefore reaching a specialist audience) or published in a language other than English (reaching a wider audience). The underlying principles that govern co-publication include the following:
Co-publications may take one of the following forms:
Before proceeding with a co-publication, authors must also consider that the editor of the other journal may consider the publication to be redundant (duplicate) publication, that is, "publication of a paper that overlaps substantially with one already published in print or electronic media" (ICMJE recommendations on overlapping publications; accessed 22 August 2018); and that the authors of published Cochrane Reviews have granted Cochrane an exclusive licence for publication for the Cochrane Review, and the journal editor needs to be aware of this to ensure that the journal licensing does not impose restrictions on the original licenced content.
It is likely that a co-publishing journal will request that the abridged version of the Cochrane Review is peer reviewed and edited according to the journal’s editorial process, and it is possible that the authors will receive additional edits or feedback as part of this process. If appropriate, authors of the Cochrane Review should take these changes into account in the next update of the Cochrane Review. If, during the journal peer review process, authors are asked to change the way they present the review data (e.g. the results and/or conclusions change) in comparison to the CDSR version, the authors should discuss this with the CRG (and Editorial Methods Department, if necessary).
Note that if an original commentary is published alongside the co-publication, the journal must ensure to clearly differentiate between the author(s) of the commentary and the author(s) of the Cochrane Review (i.e. it should not appear that a Cochrane Review has been published by a different set of authors).
Authors considering co-publication of an updated version of a Cochrane Review must also consider the following:
Occasionally Wiley and the Cochrane EMD request to have sight of the proofs of the review article prior to publication. This is on a case-by-case basis and is primarily intended to ensure that co-published versions of the Cochrane Review adhere to the current co-publication policy.
For permission to co-publish an updated version of a Cochrane Review, please contact the Managing Editor of your CRG, using the ‘Permission to co-publish’ form (see Co-publication forms); your case may be referred to the Cochrane Editorial & Methods Department and Wiley for further guidance. The guidance given in the following section should also be followed: Arranging co-publication of a Cochrane Review.
