Crossmark policy page

Crossmark is a multi-publisher initiative from Crossref to provide a standard way for readers to locate the current version of a piece of content. By applying the Crossmark logo, Portland Press is committing to maintaining the content it publishes and to alerting readers to changes if and when they occur.

Clicking on the Crossmark logo will tell you the current status of a document (i.e. whether the article is current or whether updates have been published) and may also give you additional publication record information about the document.

Additional information about Crossmark can be found on the Crossref website.

Correction and retraction policies

Corrections are published in Portland Press journals to provide a means of correcting errors of omission (for example, if a citation or an acknowledgement is missing) and errors of a scientific nature that do not alter the overall results or conclusions of a published article. Prior to publication, corrections of a scientific nature are sent to the Editorial Board member who handled the paper through the peer review process to review and approve. To publish a correction, all authors on the article must be aware of and agree to publication of the correction. To submit an author correction, an email with details of the correction should be sent to the Production Team.

When a correction is published, the original version of the article remains available and there is a note to say that the paper has a correction. A link from the article to the correction is displayed.

Retractions are published in Portland Press journals when there are major errors in a paper or ethical misconduct that calls into question the data presented and/or the validity of the results presented. Portland Press works with the Editorial Board of the journal in order to decide whether a correction or a retraction is appropriate, and where a retraction is considered the most appropriate course of action, Portland Press works with the authors of the paper to prepare and publish the retraction statement.

All authors on a paper must be aware of and agree to publication of the retraction. If authors do not agree with the retraction of their paper, the Editorial Board of the journal is able to make the final decision to retract the paper indicating in the retraction statement that the authors did not agree to the retraction. To submit a retraction, an email with details of why a paper should be retracted should be sent to the Production Team.

When a retraction is published, the original version of the article remains available and there is a note to say that the paper has been retracted. A link from the article to the retraction is displayed.
