Assistance for first semesters regarding the use of the library, research etc., can be found under "Introduction and Help" (< Link).
Dissertations from the University of Lübeck are archived through the Zentrale Hochschulbibliothek and can be recorded digitally, if desired. Under "Publishing" (<Link) you can find further information for the requirements.
