In 1985, the National Library launched the bibnet.lu network of Luxembourgish libraries. Today, this network brings together around 90 libraries from cultural institutions, universities and schools, public libraries and specialist libraries.

The National Library coordinates the bibnet.lu network and ensures its smooth operation. Together with the Centre des technologies de l’information de l’État (CTIE), it develops and maintains the digital tools used by all members. The network also works closely with the Consortium Luxembourg.

The collections of all participating libraries are brought together in a shared online catalogue, accessible via the search engine a-z.lu.

The National Library coordinates the Consortium Luxembourg. This body is responsible for acquiring and managing digital publications. Its tasks include administrative management, software operation, access to resources, as well as negotiating licences and subscriptions.

The Consortium brings together several partners, including the University of Luxembourg, the Luxembourg Institute of Science and Technology (LIST) and the Luxembourg Institute of Health (LIH). It also works in cooperation with the Luxembourg Centre for European Law, the Luxembourg Institute of Socio Economic Research (LISER), the Institute for National Education Training (IFEN) and SCRIPT.

In 2017, the National Library launched bibgov.lu, the government library, in cooperation with the Ministry of the Civil Service and the Centre des technologies de l’information de l’État (CTIE). This service provides specialised digital resources for ministries and public administrations.

The Consortium Luxembourg also coordinates the ebooks.lu project, a free lending service for e-books and audiobooks in French, German and English. It is accessible to users of the National Library, the Bicherbus, and several public libraries across the country.

The National Library is a member of the High Council of Libraries and provides its secretariat.

The amended law of 24 June 2010 on public libraries establishes for the first time a legal framework for public libraries in Luxembourg. It applies to municipal and non profit libraries approved by the minister responsible for Culture, and not to all libraries funded by public money.

To obtain this approval, public libraries must meet several conditions, including mandatory membership of the national network of Luxembourg libraries.
