Changes in society are reflected in librarians' daily work which means they have to continue to develop their competencies after their education in library and information science. Continuing professional development (CPD) via digital resources is a contemporary form of CPD that comes with both opportunities and limitations. The aim of the study is to deepen the knowledge about public librarians' experience with CPD with focus on CPD via digital resources. The study has a focus on Digiteket, which is a digital learning platform that is relatively unexplored. The theoretical framework of the study consists of the concepts of CPD and professional learning experience from which the theoretical tools have been drawn. The theoretical tools consist of a table of CPD methods and activities and also personas, which are used in the analysis. The empirical material of the study consists of semi structured interviews with five public librarians. The result shows that Digiteket is used in a variety of ways and to varying extent and that there are limitations with the plattform. Other digital resources are common for CPD and time and resources are two adversities for CPD opportunities. Self-directed and informal methods and activities were the most common, and the curious ad hoc learner persona corresponded the most with the respondents, which was shown in the analysis and conclusions. Another conclusion was that Digiteket was not the most used resource for CPD among the respondents.
