The project aims to investigate the question of how discussions in social media on topical issues that are difficult to grasp and by their very nature are not intended to be permanent can be made fruitful for historiography. When utilising this data for research, there are various challenges in terms of data quality and data access, as well as the risk of data loss and changes in meaning. However, the preservation of this digital ephemera is necessary as it represents an important form of collective memory. The proposed project aims to address the methodological challenges involved in working with ephemeral data for social science research and in archiving and documenting important contextual information.
