The National Library of Luxembourg collects, catalogues and preserves all analogue and digital publications published in Luxembourg and any works published abroad that relate to the Grand Duchy. It is the country’s leading academic, research and cultural heritage library.

The Luxembourgish Collection consists of all printed or online publications edited and produced in Luxembourg after 1800, entered by legal deposit and acquired in addition to legal deposit. The collection also includes works published abroad by citizens of Luxembourg, or which are connected with the Grand Duchy of Luxembourg or the former Duchy of Luxembourg.

In order to meet the requirements of its users, about three-quarters of its printed collections come from other countries and they cover different fields of knowledge. The Non-Luxembourgish collection covers numerous areas of knowledge and encompasses books, periodicals, congress and conference proceedings, reports, studies, reference works and science popularisation writings.
