The article describes a case study of lifelong e-training for postgraduates delivered jointly by the Carlos III University of Madrid and Spain's National Library from 2011 to 2017. It addresses course and participant characteristics as well as the results of an assessment aimed to determine both student satisfaction and effective skill transfer to the work environment. This unique professional training initiative may serve as a model in an area where librarians and professors are seldom seen to collaborate in online training on an equal footing.
