Basic principles

The National Library is required by law to preserve its documents in their original form. Conservation measures are implemented to extend the life of these valuable cultural assets.

Prevention

Underground stacks, durable bindings and protective packaging help the National Library keep its documents in the best possible condition.

Preserving originals

The National Library preserves the original documents in its collections using paper deacidification, book repairs and restoration.

Surrogate media

The National Library can create copies of original content on surrogate media. The documents most at risk from paper decomposition are newspapers.

Archiving

The National Library’s collections are kept in two underground stacks, which have sufficient space to meet archiving needs until 2038.

Tips on preserving your own documents

The National Library can offer you advice and support on preserving your own valuable documents and treasures on paper.
