ИНИОН (i.e., INION) stands for Институт Научной Информации по Общественным Наукам, i.e. The Institute of Scientific Information for Social Sciences. Since this institute is a unit of the Russian Academy of Sciences, the database is listed as "Russian Academy of Sciences Bibliographies" in most Western libraries.
Russian Academy of Sciences Bibliographies is a very large and extremely useful database, especially for Russian-language materials. Containing over 1,200,000 records for articles, books, manuscripts and dissertations in the humanities and social sciences published since 1980, INION offers a breadth of bibliographic access to Slavic and East European journal articles that is not approached by any other single database.
12,500+ journals indexed, primarily from Russia, the CIS, and Eastern Europe. These journals are listed on INION's own website (see below for more details) at
