In the wintersemester 2006/07 the University Duisburg-Essen offered an International Course of Lectures in English. The lectures took place two-weekly on Wednesday from 12 a. m. till 3 p.m. and were streamed into the internet. So students and experts from all over the world could take part just in time. Students and experts who were available were welcome to visit the International Course of Lectures in the Library Hall (Bibliothekssaal) at the Campus Essen.
