In addition to the Open Access Repository MACAU, Kiel University Library operated another repository under the name Journals@CAU until the end of 2021. On this, the series Kiel Computer Science Series and Report of the Institute for Computer Science as well as digitized versions of the historical Staff and Course Directories of Kiel University from 1665 to 2000 were published.

The operation of Journals@CAU has been discontinued. The two series were transferred to MACAU. The Staff and Course Directories can still be reached under their existing URLs.
