How can I post my preprint?
Click on the submit preprint button at the top of the page. You will need to create an account if you don’t have one already. Our editors will check the suitability of your paper and most can be posted within 24 hours.
Is my article suitable?
Preprints focuses on original research articles and comprehensive reviews. Editorials, discussion papers, and commentary are usually not suitable. Papers should not have been published in a peer-reviewed venue before, and we recommend against publishing the same paper on multiple preprint servers. See the instructions for authors for more details.
Will a preprint I cite disappear, can preprints be removed?
Preprints with a registered DOI cannot be removed. Please check the withdrawal policy carefully before posting your work. Preprints with a DOI are intended to be permanent, citable objects, so if they are frequently changed or removed they cannot be reliably cited. We therefore restrict the conditions under which they can be removed from our website.
Will a journal accept my paper if it has appeared as a preprint?
In most cases, journal publication will not be affected by posting a preprint. However, there are some publishers that do not consider papers that have already appeared online. We strongly recommend that you check all journals that you might submit to in advance. The preprint policies of many journals and publishers are available on the Sherpa Romeo database.
Who owns Preprints and how is it funded?
Preprints is fully owned and funded by MDPI, an open access journal publisher. It is run on a non-profit basis. You do not need to submit to an MDPI journal in order to post a preprint here, any work is welcome. If you do submit to an MDPI journal, you will be invited to submit to Preprints.org during the submission process.
