Accompanying the documentation was a list of the contents of the boxes. This list resides in the documentation management file. The documentation consists of numbered boxes (1-50). Box numbers 1-9, 29-31, 33-35, 41-42 and 49 are missing. However, the contents of the missing boxes are described in the list. Nos. 1-8 would still be with the agency according to the acquisition form. Inquiries to Van den Berg Kruisheer Elffers, however, yielded nothing.In the inventory, the items have been described by using the descriptions in the list and by consulting the items. The descriptions are arranged within a common archival scheme for the NAI. Almost always the components described in the list have been left intact. Only here and there have components been combined or split. No items have been destroyed.
