The first volume of the overall project, ‘Map Archive and Comprehensive Database of the Dresden House Register, 1495 to 1896’, forms the foundation of the entire digital catalogue. The focus is on the preservation, transcription and structuring of the index cards compiled by Carl Hollstein on the history of houses and ownership in Dresden’s Old Town. These cards provide a concise record of changes in ownership, owners’ names, in some cases occupations and titles, as well as various historical house and plot numbers. Volume 1 makes this collection of handwritten sources – which until now has been accessible only to a limited extent – systematically available in digital form for the first time.
A key stage of the work involved the complete digitisation of the 14,929 index cards and their linking to unique identifiers. Each card was assigned a unique card ID, which enables the image file and data record to be linked. The content of the cards was then transcribed in a structured format. Data entry was carried out with editorial rigour: all entries were recorded using a double-keying process and cross-checked to minimise transcription errors. This resulted in separate but linkable data records for personal and property-related information.
Going beyond mere transcription, the data was gradually normalised and standardised. This included the standardisation of first names, titles, job titles, street names and house numbers. Dealing with the various historical spellings, as well as the house numbering systems—some of which had already been consolidated by Hollstein—proved particularly complex. The spelling of surnames was generally retained as it appeared in the source. No individual identification was carried out. In this way, the volume combines editorial fidelity to the source with analytical usability.
The comprehensive database also serves as a research tool. It transfers the information from the maps into a data model that can be used in the long term for statistical, prosopographical, topographical and socio-historical enquiries. Of particular relevance for the analysis of historical changes in ownership is the fact that the data contains not only names and houses, but also temporal references, types of ownership and links to later spatial identifications. Volume 1 thus forms the data foundation upon which the subsequent parts of the project—concerning the concordance of house numbering systems and house information from the address books of 1839, 1840 and 1860 (Vol. 2, DOI: 10.22000/e6ggwpvy15hpzk55 ) and the georeferenced visualisation (Vol. 3, DOI: 10.22000/278zmxuhvm26gm34) .
