About ORBilu

ORBilu (Open Repository and Bibliography Luxembourg) is the institutional repository of the University of Luxembourg. ORBilu ensures global visibility for the University's academics and their collaborations. This open repository underlines the University's willingness to make its scientific work available to everyone, without financial or technical constraint and emphasises its support for the Open Science and Open Access movement.


ORBilu guarantees the long-term preservation of references and access to research output from our research programmes. Since 2012, it is a central publicly accessible reference tool and through its Deposit Mandate is the backbone to the University’s annual activity report, performance contract and for all in-house evaluation procedures related to promotions, grant applications etc.

The evolution, distribution of references and full-text publications and other statistics on the scientific output on ORBilu can be browsed and downloaded.

As an institutional repository, ORBilu ensures that our authors increase their visibility and presence on the web, and therefore improve the impact for research by making it publicly accessible. The repository forms a complete record of research output of the institution, which is freely available, and enables the evaluation of research programmes. Open repositories like ORBilu  ensure maximum return on investment, enables future collaboration and sharing of data, reduces research waste such as duplication of research efforts, and as a consequence improves public trust and transparency in research.

Principal objectives
  • To increase the visibility of the research and academics of University of Luxembourg.
  • To strengthen the Open Access policy of the University of Luxembourg by supporting the mandate.
  • To facilitate the generation of publication reports and the internal evaluation of researchers.
  • To provide the public with free and fast access to quality scientific publications.

What does the Institution achieve when its authors make their scholarly publications available freely on the Internet?

  • Increased visibility and presence online.
  • Increased societal impact for research.
  • The open access collection in the repository forms a complete record of the research output of the institution in an easily accessible format. It provides the means for the institution to manage its research programmes more effectively and to measure and assess, if so desired, its research programmes.
  • Open repositories publicise an institute’s research strengths, providing maximum return on research investment.
  • Open repositories increase impact and usage of institute's research, providing new opportunities for collaboration.

Furthermore, as an integrated and centralised management tool, ORBilu guarantees the long-term preservation of the Institution's research output:

  • Institutional management and responsibility of references and full texts, reducing the burden for researchers and their departments without the need for their own distribution infrastructures, and also avoid having to assume the associated costs and technical maintenance;
  • A guarantee of the long-term preservation of references, their absolute access, notably independent of the evolution of research equipment;
  • A centralised reference tool, allowing everyone to follow the evolution of the Institution's research output.

Increasing the availability of full-text peer-reviewed research articles broadens dissemination, increases use and enhances professional visibility of your scholarly research which in turn can lead to increased citations and usage. ORBilu will facilitate an expansion in the development and distribution of your research on a global scale and a strengthening of the prestige and influence of your research by :

  • Increasing visibility of your work providing an increased potential for citation.
  • Making your work easily accessible to others on the web - your publications will be harvested by search engines such as Google Scholar, etc. and therefore, will be available for easy discovery.
  • Enabling more rapid communication between peers and make the development of expert networks easier.
  • Opening up new potentials in terms of new readership.
  • Preserving your scientific production, for the future, safe from loss or damage.
  • Reducing your workload:
    • You can store all your publications in a single place accessible from anywhere.
    • ORBilu can feed into researcher profile web pages and lists and reports can be exported for various purposes (ex: curriculum vitae, requests for funding, etc.).
  • Permitting you to maintain ownership of your work and who has access to it.
  • Allowing you to give permanent direct links to your work and, for restricted access items, easily respond to requests for electronic copies.
  • Providing you with usage statistics for your publications (for example: the number of views and downloads per month, country, etc.).
  • Providing explicit evidence of documents having been subjected to a peer-review process.
  • Allow you to actively participate in a fully expanding international movement which aims to enable you, researchers, to regain control of the distribution of your scientific production.

All these advantages require only a minimal effort on your part. ORBilu was effectively conceived to offer a powerful, quick and easy repository process, enhanced with automatic help tools and import and export possibilities. The depositor also benefits from, among other things, legal information in terms of copyright and ownership in publishing.

Research journals are the source for cutting-edge knowledge in every field from history to medicine yet students, researchers, professors, and others are denied access because they or their institution can’t afford it. Journals have become increasingly expensive to the point where your library cannot subscribe to everything that is relevant to your studies.
What’s the solution? Open Access. Open Access is free, immediate, online access to high-quality scholarly research coupled with unrestricted rights to use it in new and innovative ways.
How does ORBilu support Open Access and thus help you get access to the research you need?

By providing:

  • Free and rapid access to scientific publications of high quality.
  • A means of easily following the Institution's current academic research via statistics, viewing the Top 20 papers published, the ability to see Researcher profiles, and all publications in a specific discipline etc.
  • Access to a simple research interface, with the possibility of searching within the full text of the publication.
  • The possibility of finding the Institution's publications without the need of an ORBilu site search, thanks to extensive referencing in search engines and discovery tools.


It's compulsory for all researchers at University of Luxembourg to submit their publications to its open archive, ORBilu.

This mandate currently requires:

  • Researchers add the full-text electronic copies of all their peer-reviewed journal articles as well as papers from published conference proceedings in the University's digital repository immediately upon acceptance for publication (maximum delay: 1 month). This requirement applies to any articles and/or papers published since 1 January 2009;
  • Researchers add the bibliographic references of all their scientific production published since 1 January 2009 in the University's digital repository.
  • That only references from publications submitted to ORBilu be used for the internal evaluation of researchers.


Who submits? The University of Luxembourg authors themselves or the representative appointed for this purpose. If there are several UL co-authors for a single publication, only one of them has to make the deposit.
When to submit? As soon as the publication has been accepted by the publisher. It may be marked "in progress" at the time of submission if the year of publication is not certain. A publication that has been submitted to a publisher but not accepted must never be submitted as if it has been published or is a work in progress.
What can be submitted ? All publications and articles written by University of Luxembourg members. Just make sure you choose the right document type.

In addition, when you add the full text of your publication ORBilu allows you to upload 3 versions (check what you are allowed on the small point of your licence):

  • 3 versions:
    • Publisher’s postprint: Edited, formatted and published by the publisher. This is the document of choice for all publishers who allow open access.
    • Author's postprint: A revised version that has not been formatted by the publisher. This is preferable if the publisher's postprint cannot be submitted.
    • Author's preprint: Version submitted to the publisher, unedited and unformatted. This type of document can be submitted if neither the editor's postprint nor the author's postprint have been approved
  • With 3 levels of access:
    • Open Access: document immediately available to everyone (open access)
      • Open access with embargo: document accessible to everyone (Open Access) but only after a period of time imposed by the publisher. As long as the embargo date has not been reached, the document will have restricted access.
    • Restricted access: document directly accessible to University of Luxembourg staff with a request for a print-out possible from external parties.
    • Private access (for appendices and research reports): document accessible only to the authors of the publication (possibility to request reprints).

You can submit publications prior to joining University of Luxembourg but in this case you must fill in the affiliation which is in the publication itself.
