Pre-prints, post-prints and other versions

I Open Access you normally distinguish between three different versions of a journal article: pre-prints, post-prints and publisher's version. This is the terminology we use at DTU Library - but many others may also be used: 

  • Pre-print - author's original version, submitted manuscript.
  • Post-print - author's accepted manuscript, accepted author manuscript, pre-proof, author's original version.
  • Publisher’s version - published version, publisher’s version, final version.

Pre-print



 

A pre-print is a draft of a scientific article. It has not undergone peer review and is rarely identical to the final, published article.

The non-peer-reviewed articles may as a rule be uploaded to research databases such as DTU Orbit with Open Access - typically without embargo.

However, they rarely meet the grantors' Open Access requirements. As a rule, the grantors only accept a peer-reviewed version - i.e. either a post-print or a publishing version. 

 

Post-print



 

A post-print is the latest manuscript version and it has been through the peer review process. It is approved for publication, and the intellectual content is identical to the final publisher version - it just is not provided with the publisher's layout and logo.

In many cases, this version can be uploaded to research databases such as DTU Orbit with Open Access - typically after an embargo period of 6-24 months.

Select the correct one

Since both pre- and post-prints are manuscript versions without layout and logo, it can be difficult to determine the version, and many people mistakenly use the term pre-print for both submitted and accepted manuscripts. However, there is a big difference in where and when you can make pre- and post-prints Open Access, and from a reader's perspective it is important to know whether a manuscript has been peer reviewed or not.  

 

Publisher's version



 

A publisher's version is the final published article as it appears on the journal's website. It is provided with publisher layout and logo. Unless the article is published in an Open Access journal (Golden Open Access), or the article is payed Open Access (Hybrid Open Access), this version is rarely to be published Open Access.

  

When a post-print is released in DTU Orbit, it is provided with a front page, a cover sheet, with the article's bibliographic data (title, author name, journal, year, issue, page number, etc.). This cover sheet ensures that the publication is quoted correctly, even if the reader only has access to the post-print, where the bibliographic data may be deficient.

Publication types other than articles

Open Access publishing of publication types other than scientific articles (e.g. books, reports and conference papers) is more unclear. Here, DTU Library is dependent on the information available on the publisher's or conference's website.

DTU Library usually provides Open Access to unpublished conference articles (e.g. abstracts, papers and posters), unless they are subject to payment, code-protected and / or if the authors have made us aware that Open Access may not be granted.

As a starting point, a PhD thesis is archived with Open Access in DTU Orbit. DTU PhD office sends the thesis to DTU Orbit and informs about any restrictions and embargo periods.

The international non-profit organisation has developed a range of standard licenses, that can be used by people who make digital content and it gives researchers and others the possibility of totally or partly sharing their work.

With a Creative Commons license you can tailor you copyright  and give a user the possibility of making use of the research without having to make an individual agreement.

By default an author does not give his or hers rights to publishers that make Open Access journals. Instead, you are asked to license your article with a Creative Commons license.

DTU recommends that you use the least restrictive license called CC-BY (CC Attribution 4.0) which also ensures credit by citation.
