The ENR file format is a bibliographic data container developed by Clarivate for the EndNote reference management system. It facilitates the transfer of citation metadata, including author names and publication titles, from online databases into personal research libraries. Historically based on the legacy Refer tagging system, these plain text files lack executable scripts or macro capabilities, making them a secure medium for scholarly data interchange across various platforms.
