After making the placement list of the archive, inventory work began in 2006. The material is divided into the following categories:1.Personalia2.Professional practice3.Committee work and ancillary activities4.Lectures5.Publications6.Collected papers7.Appendixa. Lists of works nb these are not digital but are located under application number d1016.Most sections are arranged by year. Only the project files described under 'professional practice' are arranged by work number. Project files for which the work number is not known are arranged by year.The documents that were in the same folder or box before inventory have been packed together in a new cover as much as possible. As a result, both drawings and written documents from one project may have the same application number. Separation took place only when this was not possible for material technical reasons (e.g. photographs and slides are always packed separately).The drawings on rolls are packed as found in the tubes. Please note that the drawings are often damaged and/or stick together due to the use of adhesive tape.Also, the descriptions as stated on the folders and boxes have been reproduced as much as possible in this inventory.
