The standard type of co-publication would be post-publication. In exceptional cases, same same-day publication publication may be requested but this is subject to approval by the Cochrane Editorial & Methods Department (EMD; If you wish to discuss alternative suggested co-publication arrangements, please contact the EMD. The authors, the CRG, and the journal will all be required to follow the guidance set out below.

To initiate the co-publication of a Cochrane Review, the authors of the review should first contact the Managing Editor of the relevant Cochrane Review Group (CRG) using the 'Permission to co-publish' form; see Co-publication forms and templates. Authors should be aware that, even if such a co-publication agreement is in place with the journal, the Cochrane Review article is likely to go through the journal’s own peer review and editorial process, in addition to the Cochrane Review Group's (CRG's) processes. CRGs are encouraged to work with journal editorial teams that maintain a co-publication agreement, so that the process can be made as efficient as possible. Authors who submit a co-published Cochrane Review to a journal that already has a Cochrane co-publication agreement do not need to request permission from the Cochrane Review publishers (John Wiley & Sons, Ltd.) or the EMD, but they must complete the ‘Permission to co-publish’ form (see Co-publication forms and templates) and send this to the CRG’s Managing Editor, copying in  Cathryn Fowler; cfowler@wileyGeorgina Smith, Associate Journals Publishing Manager, Wiley, If the CRG agrees to proceed, the authors should forward the completed form to the EMD for their information (contact, ensure that the subject line of the email clearly states “Co-publication query”).


If the journal has already signed a Cochrane co-publication agreement (see Co-publication agreements with other journals), the CRG can grant permission without referring the case to the EMD ( and Wiley (Cathryn FowlerGeorgina Smith, Associate Editor; cfowler@wileyJournals Publishing Manager,, although the CRG must ensure that both are aware of each permission granted by sending them a copy of the completed ‘Permission to co-publish’ form (see Co-publication forms and templates).

If the journal has not signed a co-publication agreement, the request will be referred to the EMD for permission (ensure that the subject line of the email clearly states "Co-publication query"). The EMD will ask Wiley to either approve this as a single request or approve this and enquire whether the journal would be interested in setting up a Cochrane co-publication agreement to cover future activities. The EMD or Wiley will inform the CRG of the decision, and the CRG will communicate the decision to the author. The co-published review must meet all requirements set out in below.


The CRG must refer all same-day publication requests to the EMD and Wiley for approval using the ‘Permission to co-publish’ form (see Co-publication forms and templates), regardless of whether there is a co-publication ageement in place.
