The RI OPAC is a freely accessible literature database for medieval research in the entire European language area, covering all disciplines. The database serves as a digital directory of cited literature for the Regesta Imperii (Academy of Sciences and Literature, Mainz). It is also a universal research tool for searching for publications from the 16th century to the present day.
The entire RI OPAC is integrated into the historicumSEARCH search portal, with the exception of titles on antiquity. Please note that the RI OPAC has only been integrated into the new historicumSEARCH search interface, which is currently still in beta status.
