DNNT is a collection of works not available on the market that includes full texts of approximately 150,000 documents published in the Czech Republic until 2003 (for books) and 2013 (for newspapers and magazines). The documents made available in this way are still protected by copyright law (i.e. 70 years have not passed since the death of their authors) and are not available on the market.

In addition, the full texts of documents are available, which are free from the point of view of copyright and are marked as public works.
