When transferred to the NDB (NAI), many of the drawings were loose in boxes and bags. Many pieces concerning execution had become mixed up. The so-called "old order" had been disturbed in a physical sense.During the processing it turned out that by no means all projects had been assigned a work number. Whether a project had been executed or not did not appear to be a criterion. Moreover, the documents in the archive were arranged in such an inconsistent manner that it was neither possible nor useful to restore the old order.Therefore, I assigned an application number to all projects to be distinguished and did not follow the existing work numbering system. The corresponding documents are kept under the application number.I have left the series of correspondence intact and given each letter, or group of letters, its own application number. The correspondence pieces from the binders were put in separate covers, with the request number on the cover marked with a ° -sign. I have included the series of specifications in the project administration series, since most of the specifications could already be found there.The arrangement of the projects in the inventory is chronological. This approach offers a number of major advantages for consulting the archive. All drawings and part of the construction documents are now placed under one application number. Further correspondence can initially be found in the alphabetically ordered series and, after some detective work, perhaps also in the chronological series.At the end of Part II of the inventory, two appendices are included. The first appendix is a list of documents to be considered for destruction. This includes duplicates and other material that does not provide insight into the design process, such as financial records and advertising flyers. The second appendix includes concordances from work numbers and specifications numbers to application numbers and vice-versa.Finally, you will find an index by place name, with reference to year and application number.Note: There are no restrictions on the public accessibility of the archive.
