Open educational resources (OER) are becoming established in the higher education area concurrently to open practices in science and research. Open Education Austria Advanced, a project of Austrian universities, supports this with the joint development of attractive solutions for OER: further development of local OER repositories and a meta search engine (OERhub), and accompanying measures such as certification, qualification and knowledge transfer between participating and interested universities. The successful implementation of this project requires an interdisciplinary team and the cooperation of e-learning centres, central IT services and libraries. The following contribution discusses the work at this intersection, including the different approaches and requirements of those involved.
