Embargo

Embargo is the time period that must pass before an article can be released with Open Access. Publishers impose embargo periods to protect their business model. The length of the embargo periods varie depending on the journal, but typically the embargo is 6-24 months.

Embargo periods in DTU Orbit

DTU Library ensures that manuscripts in DTU Orbit are made available Open Access as quickly as possible and in accordance with journal and publisher guidelines. If a publisher imposes embargo periods on post-prints, for example, DTU Library will add the embargo information to the DTU Orbit record and when the embargo ends, the post-print will be released with Open Access.
If a full text version is under embargo, you can see this information including release date in the individual DTU Orbit record.

Most journals have clear guidelines for Open Access. You can check out embargo periods on the platform Open Policy Finder.

Other publication types
When it comes to other publication types (e.g. books, reports and conference contributions) the situation is not so clear-cut. Here, DTU Library depends on the information available on publisher or conference websites.

Conference contributions
In most cases, DTU Library will provide Open Access to unpublished conference contributions (e.g.  abstracts and papers) unless they are subscription-based, password-protected and/or of the authors have informed the Library that the paper in question must not be made Open Access.

PhD theses
PhD theses are usually uploaded in DTU Orbit with Open Access.

Embargo periods and funder requirements

Many funders have strict policies when it comes to embargo periods. If there is a discrepancy between the funder's Open Access demands and the author's contract with the publisher, is it the author's responsibility to obtain the necessary rights. There might for instance be discrepancies regarding the length of the embargo period. Discrepancies between funder requirements and publisher policies may sometimes be handled by making an appendix to the original agreement or by only granting the publisher the rights to publish the article (so that the author retains the right to provide Open Access to his/her work in accordance with funder requirements).

Embargo periods in DTU’s Open Access statistics

In DTU’s publication statistics, you can see which publications are currently placed under embargo and which publications still lack a post-print (i.e. accepted manuscript without publisher logo/layout).

You find the embargoed publications by clicking on the category Embargoed Open Access.

You find the publications that are not embargoed or available Open Access by clicking on the category "Closed".

The embargo typically begins the day the article is published. DTU Library sometimes receives post-prints long before the article is visible anywhere. Such articles will be categorized as closed in the statistics. Only when the article is published "for real" with page numbers, volume, and issue information can DTU Library add an embargo period to the DTU Orbit record. After embargo information has been added, the article will be categorized as Embargoed Open Access in the statistics.

Not all journals allow green Open Access. Even if authors have sent in a post-print. DTU Library may not be permitted to provide Open Access to the publication.

In other words, an article may be found in the closed category even if a post-print has been added to the record. If you are in doubt about the embargo information in DTU Orbit, contact DTU Orbit at orbit@dtu.dk
