The experience of the CSAL in creating, maintaining and using the authority file of names of sectoral organizations is discussed. The characteristics of the authority file and information sources are given, methodological solutions for data generation are considered. The authority file is used to improve the quality of bibliographic entries by unifying access points, improving the processes of in- formation exchange and retrieval. Based on the authority file, the reference and information resource has been formed – the database “Authority File of Names of Scientific Institutions of the Agroindustrial Complex” is freely accessible via the Library’s website. The authority data on the names of scientific agricultural institutions include reference information and historical data, provide access to bibliographic information, connect resources within the single data network and enable to navigate the CSAL resources. The development of the authority file content and technology is reviewed. The content of the authority file is updated on the basis of the library collection and monitoring of data on organizations in external sources; besides, the new entries for the names of modern scientific agrarian institutions and agricultural institutions established in Russia in the 19 th century are created. The OPAC-Global ILS replaced the earlier CSAL automated library and information system software, therefore the authority file was transferred into the new software environment.
