A workshop on data science and digital collections was held in December 2019, aimed primarily at staff from research libraries, who provide services and support to researchers, students and other library users. The purpose of the workshop was to provide information and create an understanding of how to access and use the digital collections. Specifically, how to use APIs for searching and extraction of data in order to foster these competencies. Workshop programme, presentations and instructions are included.
