In order to obtain access to OSA Archivum on-site collections, researchers need to register by completing our Registration Form and by agreeing to our Researchers' Statement on the lawful use of archival records.
Upon arrival at OSA Archivum, the researcher should present a valid ID or passport to obtain a Research Card.
The Research Card is valid for two years. During this time, the OSA Archivum records researcher visits and requested records; this data helps us to expedite requests and to improve the quality of our services over the long term.
