ORBi Referencing

Our publications are visible and not only on ORBi...

Since the beginning of ORBi, particular attention has been given to its referencing in quality tools, our desire being to automatically "push" UMONS references everywhere where researchers from all over the world go to search for scientific information.

This visibility goes, of course, through the essential web tools such as search engines but also through more specialised tools such as Open Access harvesters, library catalogues or social networks.

A publication on ORBi is just a few clicks away from being distributed as widely as possible!

Via general or specialised search engines

Web visibility naturally requires strong positioning on general or specialised search engines for scientific literature. 

ORBi references are therefore present and visible very quickly, not only on well-known search engines such as: Bing, Google, Yahoo, etc., but also on: 

Google Scholar

Search engine for scientific research, made by Google.

Indexing of ORBi since 2008.


General search engine. Described as the Chinese Google, it is the most commonly used search engine in China with over 400 million users.

Indexing of ORBi since 2016.


Meta-search engine created by Gabriel Weinberg (DuckDuckGo Inc.).

A philosophy committed to the preservation of privacy, no storage of personal data.

Via library websites

The references on ORBi are also indexed by Discovery tools used by thousands of academic and scientific libraries around the world.

These tools are gigantic databases that allow users to search, several hundred million references to electronic resources of a scientific nature (articles, books, chapters, reports, legal documents) via a single interface. These data are made available by publishers and content aggregators, but may also come from local sources (catalogues, institutional repositories, digitised collections).

For the expansion of its documentary collections, the University of Liège has chosen the Central Discovery Index (CDI).

Central Discovery Index (CDI)

Supplier: Ex Libris

ORBi indexing since March 2013 (via the previous index, Primo Central Index)

Ebsco Discovery Service (EDS)

Supplier: Ebsco

Via Open Access search tools

Besides Google Scholar, there are several other search engines specialising in scientific information. These powerful engines rely on the Open Archives Initiative (OAI) metadata sharing protocol to harvest various sources (institutional repositories, open archives...).
