PLOS publishes corrections, retractions, and expressions of concern as appropriate, and as quickly as possible. We follow the ICMJE (http://www.icmje.org/) and COPE (http://publicationethics.org/) guidelines where applicable.
A notice of correction will be issued by PLOS to document and correct substantial errors that appear in online articles when these errors significantly affect the content or understanding of the work reported (e.g., error in data presentation or analysis) or when the error affects the publication's metadata (e.g., misspelling of an author's name). In these cases, PLOS will publish a correction that will be linked to the original article.
In very rare cases, we may choose to correct the article itself and re-post it online. If that course is taken, a correction notice will also be created to document the changes to the original article.
Authors who wish to alert PLOS to a situation where a correction may be warranted are requested to contact us with the relevant details (journal, full citation of the article, and description of the error) at: firstname.lastname@example.org
Authors are encouraged to post comments to their articles to note typographical errors, and other problems that do not significantly affect the scientific integrity of the work.
PLOS Journals now participate in the CrossMark service, which is a multi-publisher initiative to provide a standard way for readers to locate the most up-to-date version of an article. By applying the CrossMark logo PLOS 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 and may also give you additional publication record information about the document.
