What is a Semesterapparat (course reserved reading)?

The University Library reserves and compiles a set of media for lecturers for seminars, lectures, and similar events. This is called a Semesterapparat. These are usually available at the departmental library of the lecturer’s department. For example, a lecturer of pedagogy would order a Semesterapparat from the Departmental Library of Educational Science, Philosophy, and Psychology.
Semesterapparate are usually available for the duration of a semester. The books in them are not for loan and are marked as such in the catalog.
