On occasion of Johannes Gutenberg-University's 70th anniversary this collection presents digitized printed works and other documents which are closely connected to Mainz University's history. The digitized documents refer both to the history of the old Mainz University (1477-1798/1823) and Johannes Gutenberg-University Mainz which was founded in 1946. The collection will increase continuously. We start with the old Mainz University's directories of professors and students as well as Johannes Gutenberg-University's rectorate reports.
