Making a legal deposit of a publication with the National Library of Luxembourg

The National Library of Luxembourg (Bibliothèque nationale du Luxembourg - BnL) archives all material published within the territory of Luxembourg—as well as material published abroad concerning Luxembourg—that is submitted to it for legal deposit.

A publication is defined as any document, be it paper or digital, that is generally produced in multiple copies for the purpose of being made public, even if the target audience is restricted.

The legal deposit is compulsory and must be made before a claim is made by the BnL.

Each year, the BnL compiles the national bibliography of the publications deposited with it.

Who is concerned

The natural or legal person who is required to submit the legal deposit is:

  • the editor or their representative; or
  • the printer, producer or author of the publication.

In the case of doctoral dissertations, application papers and research papers, legal deposit copies are submitted by the public or private institution that is the recipient of the documents.


To be subject to the legal deposit requirements by the National Library of Luxembourg, a publication must be edited in Luxembourg, which is to say:

  • any publication by an editor (natural or legal person), or failing this, a printer, a producer or an author either residing in Luxembourg or having their registered office in Luxembourg;
  • any publication created in Luxembourg by an editor (natural or legal person), or failing this, a printer, a producer or an author either residing abroad or having their registered office abroad;
  • any publication, thesis or research paper whose creation was supported by a public sector body in Luxembourg.

The publication in question may be:

  • printed and graphic: books, brochures, newspapers, periodicals, posters, calendars, musical scores, choreographic works, plays, braille publications or any other document concerning the political, economic, social, cultural, scientific, religious or tourism life in Luxembourg;
  • digital on a physical medium, regardless of the nature of that medium, and publications referred to in the previous paragraph produced by a method other than printing (e-books, e-journals, databases, software, etc.);
  • without a physical medium (publications referred to in the 2 previous paragraphs) and made available to the public via an electronic network (websites and online content).
Reissues, adaptations, new versions and different versions, as well as translations of the aforementioned publications are also subject to legal deposit.

The following publications are not subject to legal deposit, regardless of their medium:

  • printed personal document: family event announcements, personal and address cards, invitation cards and letters, letterheaded envelopes and letters, etc.;
  • printed commercial documents: letterheads, invoices, business cards, order forms, labels, instructions and user guides;
  • printed administrative documents: templates, registers, internal circulars, control sheets, forms, etc.;
  • financial securities.


Printed and digital publications must be deposited at the BnL no later than 1 month after being made available to the public.

Doctoral theses, application papers and research papers must be deposited no later than 4 months after being sent to the recipient institution.


There is no charge for legal deposit submissions to the National Library of Luxembourg.

How to proceed

Legal deposit declaration

The legal deposit declaration must be submitted using (see 'Forms / Online services').

The declaration form must be submitted with the printed and/or digital legal-deposit copies of the publications. In return, the BnL issues a legal deposit receipt to the applicant.

For newspapers and periodicals, only the first issue submitted must be accompanied by the legal deposit declaration form.

Submission of documents

Persons who wish to submit printed publications can send them by post or submit them in person at the BnL reception desk.

Digital publications on a physical medium may be sent electronically in accordance with the BnL's instructions. If electronic submissions are not possible for justified technical reasons, digital publications must be submitted on an appropriate physical medium determined by the Library:

  • in person; or
  • by simple mail.

Publications with no physical medium can be submitted as soon as:

  • the BnL has free and guaranteed access to the publication and its metadata;
  • the BnL is entitled to make a high-quality copy of the publication.

In other cases, the producer must submit, at the Library's request, any information or tools required to copy the publications.

If this type of publication cannot be submitted online for justified technical reasons, it must be delivered on an appropriate physical medium determined by the Library:

  • in person; or
  • by post.
Once the publication has been deposited, it becomes the property of the BnL which can make it available to the public.
