ULiège researchers, your publications are visible on ORBi, far from it indeed...

Since the start of ORBi, particular attention has been given to its referencing in quality tools. Our aim is to automatically “push” ULiège references to all those places where researchers are likely to go to search for scientific information.

Naturally, this visibility is achieved by using inevitable web tools such as search engines, but also by means of more specialized tools such as Open Access harvesters, library catalogues or through social networks.

In just a few clicks, a deposit on ORBi for the widest possible dissemination!

On general or specialized search engines

Web visibility depends, quite simply, on optimal positioning on general purpose search engines or search engines specialized in scientific literature.

The ORBi references are therefore rapidly present and visible on well-known search engines such as: Bing, Google, Yahoo... but also on:


  • General search engine
  • Described as the Chinese Google, it is the most widely used search engine in China with more than 400 million users
  • Indexing of ORBi since 2016


  • A metasearch engine founded by Gabriel Weinberg
    (DuckDuckGo Inc.)
  • A philosophy committed to the preservation of privacy, no storing of personal data

Google Scholar

  • Search engine for scientific literature, made in Google
  • Indexing of ORBi since 2008

Microsoft Academic

  • Search engine developped by Microsoft Research
  • This search engine is used mostly on the other side of the Atlantic (2nd place behind Google)
  • More than 120 million indexed publications (April 2017)
  • Indexing of ORBi since 2016

Through library discovery tools

Google is evolving, libraries are too.
Thousands of libraries around the world are encouraging their users to take advantage of the enormous potential of “discovery tools”.

As gigantic indexes, these tools mean that it is possible, by means of a single interface, to search among several hundreds of millions of electronic resource references of a scientific nature (articles, books, chapters, reports, legal documents…). This data is made available by editors and content aggregators, it can also stem from local sources (catalogues, institutional repositories, digital collections…).

Central Discovery Index (CDI)

  • Provider: Ex Libris
  • Indexing of ORBi since March 2013 (via the prior index, Primo Central Index)

Ebsco Discovery Service (EDS)

  • Provider: Ebsco
  • Indexing of ORBi since March 2016
  • The activation of ORBi in this index by 2,752 clients (March 2017)

Through Open Access research tools

Apart from Google Scholar, there are several other search engines specialized in scientific information.
These are high-performance search engines built on the OAI protocol for metadata sharing in order to harvest the various sources (institutional repositories, open archives…).

BASE - Bielefeld Academic Search Engine

  • One of the most important metaengines for accessing university resources in open access. It harvests more than 100 million references from 5,000 sources
  • Publisher: Universität Bielefeld
  • Indexing of ORBi since 2008



  • A search engine for human and social sciences, harvesting a large quantity of links from many digital libraries, more than 5 million documents from more than 4,000 sources
  • Publisher: Huma-Num (CNRS, Aix-Marseille Université)
  • Indexing of ORBi since 2012


One Repo

  • Open Access harvester
  • Indexing of ORBi since 2012


  • The European project OpenAIRE (Open Access Infrastructure for Research in Europe) aims to meet the obligation to place in open access (deposit mandates) as decided by the European Commission and the European Research Council (FP7, Horizon 2020). Access to 20 million publications, 45,000 datasets.
  • Publisher: OpenAIRE.eu
  • Indexing of ORBi since 2015


  • PubMed, the well-known search engine for biomedical sciences, comprises today (September 2017) more than 27 million citations from MEDLINE, life science journals, and online books.
  • Publisher: US National Library of Medicine
  • Integration of ORBi to the PubMed "LinkOut" tool: Mey 2017

Through social networks

Each ORBi reference:

  • automatically retweeted via the Twitter feed @ORBiPubsULiege
  • has the function “share” for easy communication on the social networks
    (Facebook, Twitter...)
  • displays the Altmetric
    (alternative measurements of impact alternatives for web casting)

Through ULiège and ORBi tools

  • Bounces from the ULiège and CHU directories toward the lists of personal publications on ORBi
  • Links from articles on the science popularization site ULiège Réflexions
  • Thanks to the reports generating module of ORBi, there is a possibility for the automatic integration of:
    • Constantly updated ORBi publication lists for personal and faculty websites
    • Web links to ORBi publications (ex. email signature, profile enrichment on social networks...)

Directories and others

The ORBi directory, as such, is referenced in:

  • OpenDOAR - Directory of Open Access Repositories
  • ROAR - Registry of Open Access Repositories

And during many years, an excellent positioning of ORBi in the Ranking web of repositories.

This tool gave a twice-yearly ranking of Open archives, of an essentially scientific nature, created based on different criteria (web presence, number of fulltext versions...).
