The openCost project was represented at the Open Access Days 2023 with two contributions. Colin Sippl (Regensburg University Library) presented a poster entitled „openCost: Transparenz von Publikationskosten durch neue Funktionen in der Elektronischen Zeitschriftenbibliothek (EZB)“. The poster was awarded the „most learned“ prize and can be viewed on Zenodo.

In addition, Lisa-Marie Stein (DESY Hamburg) reported on news from the project in her presentation „Transparent publizieren mit openCost: Neuigkeiten zur technischen Kostendateninfrastruktur“ and presented the openCost contract schema. For those who did not have the opportunity to follow the lecture live, the video recording is now available online via the TIB AV-Portal.
