This interface is used to export basic library data from CertLex. The library currently available in CertLex at the time of the export is transferred to the target program. In addition to the basic information about legal sources (e.g. short titles, long titles, etc.) a link is provided which links back to the library in CertLex. However, the link is only usable if the user logs in to CertLex afterwards, so he must be a registered user.
