The editorial staff checks all submitted manuscripts, and only those papers that seem most likely to meet our editorial criteria are sent for formal review. All forms of published correction may also be peer-reviewed at the discretion of the editor. Reviewer selection is critical to the publication process, and we base our choice on many factors, including expertise, reputation, and specific recommendations. The whole review process is conducted using a double-blind peer review method managed by the editor. The names and affiliations of authors are guaranteed to be unpublished.
