free, unlimited access
In Review is a free journal-integrated preprint service offered to authors at participating journals. Authors can opt to have their manuscript automatically posted online in the form of a preprint with a DOI.
Authors have the option to opt in to In Review directly from the submission system of participating journals.
To opt in, all co-authors agree to have their manuscript posted as a preprint with a CC-BY 4.0 license and a DOI, becoming a permanent part of the scholarly record. Read more about our editorial policies here.
Once the submission has been sent out for review by the journal and has passed the Research Square prescreen, the manuscript is converted to HTML and posted on Research Square. It will be marked as part of In Review with the journal name to indicate it is under consideration at a participating journal. If the original manuscript file was uploaded as a PDF, only the abstract will be converted to HTML.
Preprints posted on Research Square receive a DOI making them a citable part of the scientific record. They are widely indexed by indexers such as Crossref and Google Scholar, giving them a permanent digital presence. Once preprints receive a DOI, we cannot remove these without cause.
Preprints are posted within 72 hours from when the manuscript has passed journal checks.
If the author would like to have their preprint posted before it is under review, they can elect to have it posted without the journal information listed on the preprint. The preprint will be posted within 48 hours from an author selecting this option. Once the journal checks are passed, the journal information will then appear on the preprint.
Events information that is displayed in the peer review timeline is received through Research Square’s direct integration with the manuscript tracking system of journals that participate in In Review.
Readers may notice that not all In Review preprints have a peer review timeline. Journals can participate in In Review with varying levels of transparency into the peer review process, and some journals opt to not share those details publicly on our preprints.
Preprints can have the public status Under Review, Under Revision, and Published. If the submission is accepted and published by the journal, the preprint will have a link to the published version on the journal website.
If the submission is rejected by the journal, the preprint will remain on Research Square, with the journal branding and peer review timeline removed.
Authors who would like their journal-submitted revision to be posted as a new preprint version can contact Research Square at [email protected] This option is only available for manscripts that are actively under consideration at an open access In Review journal. Authors whose papers are no longer under consideration at an In Review journal can submit a revision by logging into their Research Square account.
Preprints posted through In Review may be indexed in Europe PMC, PubMed Central, Meta, and Researcher. All preprints are archived in Portico, a not-for-profit organization committed to the long-term preservation of scholarly content.

"Surprisingly, we were contacted by different journals, colleagues and press/media-houses even before the final decision from the journal. My special personal thanks to Research Square for offering such an incredible circulation of our manuscript even before the actual publication."
