Preprints

Preprint

A preprint, also known as the Author’s Original Manuscript (AOM), is the version of an article that precedes formal peer review.

 

 

Depositing preprints

Some authors may post their preprints on a preprint server before submitting to a journal to enjoy the benefits brought by preprints.

 

Benefits

Depositing preprints can bring about benefits including:

	Speed The research can become available for others to read before the final version is published. As publication times can sometimes be lengthy, this enables other researchers to see the research more quickly.
	Credit Preprint servers typically assign a DOI (Digital Object Identifie) to a preprint, which can help to create a record of research and establish primacy for the discoveries without having to wait for the final version to be published.
	Feedback Posting a preprint allows other researchers to offer feedback which may help to improve the article before the formal journal peer review process.
	Research impact The research presented in a preprint will be publicly available for other researchers to cite and build upon more quickly.

Caution

Different journals may have different policies on posting preprints prior to publication - encouraging, allowing conditionally, or restricting. Authors should always watch the journals' policies before posting preprints.

Here are some examples:

	Allowed Elsevier journals see also: Biophysical Journal Nature Portfolio journals Springer Nature journals Taylor & Francis journals Wiley's journals except clinical research manuscripts in Journal of Orthopaedic Research
	With restrictions ACM journals only allow preprints on Non-Commercial Repository or Aggregation that does not duplicate ACM tables of contents Biophysical Journal only allows preprints on a private website or on arXiv, bioRxiv, ChemRxiv, medRxiv or GitGub, but not other preprint servers or "virtual journal" websites BMJ journals only allow preprints in a recognised, not-for-profit, preprint server IEEE journals only allow preprints in a list of not-for-profit third-party servers (refer to IEEE Publication Services and Products Board Operations Manual 2023, P. 91 Section 8.1.9 A-2-6)
	Not allowed Bone & Joint journals Journal of Orthopaedic Research (Clinical research manuscripts)

The above list is not exhaustive, and only reflects the situation when the list was compiled.

For latest information, please refer to the guidelines for authors of the journals.

 

Using Preprints

Use with caution

Readers should always bear in mind that preprints must be understood as an incomplete work in progress, in which the findings presented are yet to be vetted and should be examined with caution.

For example, medRxiv displays a message to caution readers:

Caution Preprints are preliminary reports of work that have not been certified by peer review. They should not be relied on to guide clinical practice or health-related behavior and should not be reported in news media as established information.

 

Citation

The preprints discussion document (p.4) by COPE (Committee on Publication Ethics), of which many major publishers, such as Elsevier, Sage, Springer Nature, Taylor and Francis, and Wiley, are members, states that:

For journals In general, preprints are considered to establish precedence. It is relevant for authors to cite other preprints which authors have considered during research or are relevant to their work. This is in line with the expectation that other non-peer-reviewed sources such as datasets, blogs or books should be cited.

 

Nonetheless, different publishers may have different policies regarding citation of preprints.

For example, Nature states in its formatting guide that:

References Only articles that have been published or accepted by a named publication, or that have been uploaded to a recognized preprint server (for example, arXiv, bioRxiv), should be in the reference list.

Authors should always check the journal's formatting guide regarding citation of preprints.
