Refike Sülçevsi writes that since the Serbian incorporation of Kosovo in 1912, a huge numbers of valuable documents containing history were destroyed or stolen. This was done in order to hide information about the Albanian heritage in the region.

The reason of such deficiency is the long ruling of Serbs in Kosovo, since the year 1912, where a huge number of documents with the ottoman script were destroyed or were taken from the country. Due to the lack of these documents, until now, there was no proper approach; scientists of Kosovo were obliged to use documents of Serbian, Austrian, German, Italian, English, French and other archives. ed.).
