On the occasion of EERA’s 30th anniversary, we aim to put the ECER submissions at the centre of the research workshop, delving into the potentials and limitations of this corpus and presenting insights into the evolution of ECER based on these submissions. The corpus is based on a data dump provided by the EERA office and consists of more than 35,000 submissions in various presentation formats delivered to the ECER from 1998 to 2024. While this corpus offers intriguing insights into geographical, topical, network-related and temporal aspects, continued enrichment and cleansing are imperative. Five short papers deal with the ECER submission corpus from different perspectives.
