The final inventory of the Eibink and Snellebrand archives had several purposes.

First, the arrangement scheme of the preliminary inventory was inadequate. This scheme, which was modelled on a scheme intended as a standard within the NAI at the time, had as its main division a breakdown by document category.
Within the chapters, drawings, written documents and photographs and negatives of one project or design were described separately from each other. These descriptions were brought together by project or design in the final inventory.
For the activities that are not part of professional practice, the arrangement scheme also proved inadequate. Within the chapter 'Personalia' there appeared to be documents relating to travel, free work and 'true' personalia, as well as documentation. These are described in separate chapters in the final inventory. It should be noted that in practice the distinction between free work, personalia and travels is not always clear-cut.
This is further explained below under 'particulars regarding the new arrangement'.

The second reason for editing was of a physical nature. The covers used did not meet preservation requirements and were replaced with the low-acid blue covers used by the NAI. Furthermore, overstuffed covers and portfolios and boxes were thinned, and blueprints were separated from drawings.
Also, during editing, the access numbers were adjusted. The numbers are structured according to general NAI rules. You can read more about this under the heading 'user instructions'.
The correlation between the old and new numbering can be found in the concordance, attached as an appendix.

A third reason was that material in the field of arts and crafts was described only globally and in different places within the inventory, namely under designs (drawings), photographs and glass negatives. The material was studied, and described in more detail. To this end, among other things, a brief literature search has taken place, and the photographs and descriptions from the furniture catalog, the drawings, the photographs and the glass negatives have been compared. As a result, much of the material has now been described as specifically designed.
An overview of furniture described within the Furniture Catalog is attached to the final inventory. Because most of the furniture is no longer at the NAI, this overview shows where the furniture was located as of November 1999. Cross-references have been made between the descriptions in this overview and the pieces described in the inventory.

Finally, some adjustments have been made under the chapter 'Work by other architects'. 'Work of other architects' is now part of the chapter 'Professional Practice', because it can be assumed that they are included in this archive on that account. The overview is now alphabetical by name of the architect, and no longer chronological. Documents, which turned out not to be the work of architects, but documentation, are now described there.

Details of the new arrangement

General
The descriptions are arranged chronologically. Projects and designs that could not be dated are always listed at the end. An exception is the section "Work by other architects". Here the descriptions are arranged alphabetically by architect's name.

Details on personal details, free work and travel
Part of the documents relating to travel and free work concern drawings (sketches, studies), another part photographs and glass negatives. Photographs and glass negatives are partly recordings of drawings.
Within the final inventory, the descriptions of drawings were taken as a starting point. These descriptions proved to be correct. However, in a number of cases the work had been attributed to the wrong person. This has been corrected. The starting point was the signature.
The glass negatives in the CAND list turned out to be less accurate. The glass negatives were redescribed, with a comparison to the drawings. Where relevant, descriptions of glass negatives were appended to the descriptions of the drawings.
It was found that:
- recordings (glass negatives, photographs) are not present of all studies and sketches;
- a considerable number of glass negatives concern drawings (studies, sketches), which are not in the archive.
This means that, the researcher who wants to form a picture of free work, studies and travel sketches will have to consult both document categories.

CAND list lapsed as access for the (glass) negatives
For the (glass) negatives, with the completion of the final inventory, the CAND list as access to the file of glass negatives - due to proven inaccuracy - will expire. This access is now formed by this inventory.

Some descriptions of glass negatives moved to documentation
Some of the glass negatives described as personalia turned out not to be personalia, free work or travel. These are further considered documentation - material collected by the architect out of professional or personal interest - and have been described there.

Details on 'Social Action
'The chapter 'Social Action has been dropped. The descriptions here concerned only syllabi from TU Delft. No connection could be found here with the social appearance of Adolf Eibink. They have been brought under 'Personalia Eibink'.

Interior designs
Within the Arts and Crafts section, a number of interior and furniture designs have been described. In addition, there are a number of interior designs that are part of a total design (building and interior). These are described under projects.

They are:
Projects Eibink and Snellebrand
- 1921 Summer house 'De Hooiberg', Bergen (building and interior)
- 1922-1923 Shop house R. Rijnierse, Oldenburgerlaan 4 Bergen, building and interior of wine shop 'Spirited and Wines Rijnierse'
- 1938-1940 Interior of the association buildings of the NVV,P.C Hooftstraat 172-180 and Amstel 224-226 in Amsterdam
Projects Snellebrand
- 1936 Interior design of the Lutheran Church in Zutpheni
- 1956 Labour Party Headquarters at Tesselschadestraat 31 in Amsterdam, facade and interior design entrance

Competition designs
The competition designs are described as projects.
