We run several projects to preserve and improve the security and availability of our collections. By taking stock of, digitizing and photographing manuscripts, archives, book collections and catalogues, we make them more available and also protected against wear. Modern technology help to preserve our cultural heritage for the future. When the material is searchable on the web, it also becomes available to anyone, anytime and anywhere in the world. Our projects are long-term investments, often expensive, time-consuming and technically advanced. Without the financial support of foundations and private companies, these projects would have been impossible to carry out.
