A preprint is considered as an authorâ€™s version of a manuscript prior to the version accepted for publication in a journal. Authors are allowed to deposit an initial draft of their manuscript anywhere. However, authors should disclose the Digital Object Identifier (DOI) once the manuscript is submitted to the journal or at any other point during the peer review process at TPPS. If the manuscript is accepted for publication, the preprint record should be updated with the DOI and a URL link to the published version of the article on the journal website. Please note that deposition of a preprint shall not be viewed as prior publication.
