Preprint (i.e. pre-refereeing) versions of articles can be shared anywhere at any time.
Authors may self-archive the author's accepted post-refereeing manuscript on their personal websites, update a preprint in arXiv and share a copy with students and research collaborators for their personal use immediately upon acceptance.
Authors may also deposit the accepted post-refereeing version of the article in any non-commercial hosting platform such as their institutional repository, provided it is made publicly available not earlier than 12 months after official publication. In all cases an acknowledgement should be given to the published article, e.g. in the form: "The final publication is available at the TMNA webpage via http://dx.doi.org/[insert DOI]".
Authors may not use the publisher's version (final PDF produced by the publisher) for the purpose of self-archiving or deposit.
Details of the Publisher Policy are available on the Sherpa Romeo website.
