International Standard Serial Number
The International Standard Serial Number (or ISSN from the English International Standard Serial Number) is a unique international 8-digit number that identifies a periodical printed or digital publication.
ISSN allows you to identify a publication regardless of language or media.
Consists of eight digits. The eighth digit is a check number calculated from the previous seven and modulo 11.
For transliteration of Cyrillic letters into Latin, the international standard ISO 9 of 1995 is used.
The ISO 3297 standard, which defines the rules for assigning ISSNs, was introduced in 1975. At the time of the creation of the international organization, the ISSN assignment process was managed from 75 national ISSN centers, coordinated by the ISSN International Center (Eng. ISSN International Center; French. Le Center international de l'ISSN - CIEPS), located in Paris, with the support of UNESCO and the French government. The numbers are fixed by means of CIEPS in the ISDS Register (from the International Serials Data System), which is also known as the ISSN Register (Fr. Registre de l'ISSN).
The accession of countries to the ISSN has been gradual. For example, in the USSR, ISSN was standardized in 1989, since January 1, 2003 it was replaced by GOST 7.56-2002, and the Russian National ISSN Center at the Book Chamber was established at the end of 2015.
The International Standard Serial Number is a unique identifier for periodicals and a mandatory element of their imprint. Based on the digital ISSN, barcodes of publications are built. ISSN is widely used around the world: it is needed by libraries, subscription agencies, researchers and scientists working in the field of information, news agencies and so on. It allows publishers, booksellers, librarians, researchers in a world-recognized way to seamlessly distribute periodicals in accordance with demand, improve the search and order of publications, the entire cycle of creating and bringing a periodical to the consumer.
For the 2010s, the ISSN system is used in more than 130 countries. The use of the digital code printed on the publication makes it possible to:
abandon local codes;
reduce the amount of supporting documentation;
simplify the interaction of publishers with printing companies,
