On December 16, 2015, on the eve of December 18 - International Migrant Day - a practical seminar on tolerance towards migrants was held at the Center for Documents of International Organizations of the Russian State Library (named after Lenin). Libraries today are not only a place to store books, but also a communication platform where representatives of different cultures, nationalities, religions meet and have the opportunity to discuss topical issues of our time. One such issue is the topic of migration.
