There may be various reasons for this. For example, the majority of historical newspapers have not yet been digitised. Digitisation is the responsibility of our partners, the cultural heritage institutions, and it is a complex and resource-intensive process. Some digitised newspapers cannot be displayed in the German Newspaper Portal for legal reasons, others do not meet the minimum technical standards. It is also possible that the newspaper belongs to the holdings of an institution that is not yet involved in the German Newspaper Portal.
