Purpose. The aim of this paper is to present the cataloguing of postcards and their digital reproductions according to ISBD, theoretically and through examples. Approach/Methodology. The paper examines the ISBD areas of description and explains their application to postcards and their digital reproductions through three selected examples. Findings. The paper indicates the applicability and sufficiency of the ISBD stipulations to the cataloguing description of postcards and their digital reproductions. Practical implications. In order for postcards to be available in the catalogue, it is necessary to catalogue them fi rst, and in order to significantly increase their visibility and accessibility to the public, it is advisable to digitize them and publish the digital reproductions on the library website, with the appropriate catalogue records. Social implications. Older postcards from the time when photography was not widely available due to unavailability and high cost of equipment have a considerable documentary value from various aspects, such as architecture, urbanism and printing, while newer postcards have mostly a promotional-tourist function. However, both older and newer postcards can be artistically valuable. In order for these functions of postcards to come to the fore, it is necessary to make them available and accessible to the public, which can be facilitated by their representation in catalogues and by their digitization and availability of digital reproductions on the websites of the institutions that own the postcards. Originality/value. Contribution to the debate on methods of cataloguing visual materials.
