The collection of oblique aerial photographs held in the image archive consists of 4,475 motifs taken by various aerial photography companies in the 1920s/30s across the whole national territory of the German Reich. The Herder institute was able to purchase the aerial images involving the working area of East Central Europe at the end of the 1960s. Unlike the military vertical aerial photographs of the map collection, which were used for reconnaissance and observing the front, these are civil, commercial productions that mainly document city centres and districts, streets and groups of buildings, as well as individual properties and landscapes. Until now, this sub-collection of the image archive has only been accessible and searchable for users through the index catalogue in the study hall.
The following offers a current overview of the significance of this holding as a source of architectural history:

On the completion of two digitization projects in 2007, the holding could be integrated in the online database Image Catalogue, where image motifs are available in addition to the datasets of converted index cards. In order to facilitate the use of materials for both historical and current East Central European research questions, both the German as well as the Polish and/or Russian place names will be listed in the subsequent correction phase.
