About the National Library of Luxembourg

The National Library (Bibliothèque nationale du Luxembourg, BnL) is Luxembourg’s largest cultural, scientific and research library. It is a multifunctional institution that strives to enhance the value of its collections on a national and international level.


The BnL contributes to the knowledge society by facilitating access to information, offering a variety of resources based on the needs of researchers and society.


The BnL coordinates a network of 85 libraries. It aims to boost quality, share best practices and drive innovation in library management.


Through the sharing of open datasets, tools and APIs, the BnL fulfils one of its many missions: it provides free access to the broadest possible public using the newest technologies.

Open Data at the BnL

Data is a raw material that comes in different sizes and formats. However, people need tools to work with the data and developers need APIs to build great applications with ease. At the BnL, we cover all three aspects.

Open Data

Following its Open Data strategy, the BnL started to release a large variety datasets. All documents are of high quality and follow state-of-the-art standards. In addition, copyright has been cleared.

Open Tools

Over the years, the BnL has gained a considerable amount of technological experience. To share that experience, the BnL open sources software and tools that have been used and tested in its own production systems.

Open APIs

Next to the data, the BnL also provides access to several Application Programming Interfaces (APIs). APIs are ideal for developers who desire to automate tasks as well as for users who want to perform specific queries.
