The purpose of this study is to map the practices regarding open educational resources’ (OERs) development and implementation at European higher education institutions (HEIs) in the field of library and information science (LIS) during the COVID-19 pandemic and to identify the challenges and obstacles to their full and optimal utilization, both during crisis situations and beyond. A systematic literature review and questionnaire-based survey yielded results from 56 European LIS schools/departments (n = 56). Statistical analysis was performed using the R programming language, and descriptive statistics were used to quantify the data sets. The results have shown that the COVID-19 pandemic served as an impetus for the adoption of OERs, particularly in the context of digital education (DE) and remote learning. However, there is still a lack of awareness of the many benefits and opportunities they provide to higher education, as evidenced by the fact than less than half LIS schools/departments used OERs. Certain issues were identified, such as the lack of institutional policies regarding OERs, inadequate peer-review of OERs, and, in most cases, the absence of monitoring and evaluation practices for OERs. The results and insights from this study can be used to improve all aspects of OERs’ implementation and thus accelerate their adoption, both with regard to LIS schools/departments and other fields. Further research into the topic through interviews and focus groups should provide a deeper understanding of opportunities, challenges and practices surrounding the adoption of OERs in the field of LIS education.
