There are three stages of Articles in Press: Journal pre-proofs: Versions of an article that have undergone enhancements after acceptance, such as the addition of a cover page and metadata, and formatting for readability. These versions will undergo ​additional copyediting, typesetting and review before being published in final form. Uncorrected proofs: Articles that have been copy edited and formatted. They still need to be proof-read and corrected by the author(s). Corrected proofs: Articles that contain the author(s)' corrections. Final citation details, for example, volume and/or issue number, publication year and page numbers, still need to be added and the text might change before final publication. When the final published article is made available online, it replaces the Article in Press version, which no longer appears.
