There is an english foreword from page 245. The report only contains paintings because a new method has been developed for objects of applied art whereby basic documentation is first drawn up for all the objects. 1,083 objects including 696 paintings and 387 objects of applied art from the total of 4,217 objects in the NK collection have been researched so far.
Many provenances continue to display marked lacunae.
On the one hand, the fact that new archives are becoming available helps fill in these gaps and on the other, these new archives mean that the research time required for a single object has now become considerably longer than was expected when the project started. This is why the chairman of the supervisory committee turned to the Secretary of State for Culture in December 1999 with the request that the project be expanded both in terms of time and staffing. The Secretary of State has since promised the funds required in order to appoint two part-time researchers, Mrs C. van den Donk and Mrs R. van Egmond and a document expert, Mrs C. Thoen and to continue the project until late December 2002. This allows the provenance of all the objects in the NK collection to be equally thoroughly examined. Moreover, the Secretary of State has given his permission for the setting up of a website.
