What is Endnote?
EndNote is an English-language literature management
program for Microsoft Windows and macOS, which allows online searches in databases (e.g. PubMed) and the creation/management of literature databases. As part of a campus license, the University Library provides all students, lecturers and employees of the university with licenses for the EndNote reference management program free of charge.
