Contents of the finding aid book: The vast majority of the archival materials in the university archive are files, especially those of the university administration. The previous tradition in the area of faculties, institutes and chairs was not subject to a systematic concept. In the future, these gaps will also be filled. The area of certificates is mainly represented by doctoral and postdoctoral certificates (duplicate or copy). The area of official records is represented by administrative journals and business diaries (1869 - 1919, 1966 - 1969). The Collections section is represented by a newspaper clipping collection (1945 - 1996), which was taken over by the RWTH Foreign Institute. The other collections of the Hochschularchiv, such as estates, photo collections or objects, are not included in the present index. For this purpose, the university archive has its own finding aids, some of which are already accessible online. Structure of the finding aid book: The recording and structuring of the archived files in the university archive was not carried out according to archival aspects of provenance, but according to a rather factual approach, similar to the librarian indexing. The files were recorded by person and subject and kept in two separate series of index cards. The index cards were essentially created during the term of office of the scientific director Prof. Dr. Reinhard Hildebrandt. According to the Numerus Currens of the signatures, the individual file was recorded according to an archival model with title and further details (according to the content and thesaurus notes). This information was recorded on a so-called location map. These location maps are reproduced here in MidosaXML presentation format. In the absence of a separation of provenance, the information from the location maps is displayed in a complete file. The structure or classification of the entire stock is based on the order signatures and has only very general references to content, which are briefly placed in front of the individual structure levels. The original assignment of the order signatures provided for corresponding gaps for later file access and caused today's jump numbers. For the internet presentation, the file was checked for information that was questionable under data protection law.
