Index of ББК, the Library-Bibliographical Classification: the national library classification of Russia, developed by the Russian State Library, the National Library of Russia and the Library of the Russian Academy of Sciences. Books published in Russia print a BBK index next to the UDC number (udkindex), often followed by the author mark, as in 72 Д63. Indexes combine digits, Cyrillic letters and signs: territorial divisions in parentheses, form divisions after the letter я, as in 88я2 on a dictionary of psychology, and special divisions after a hyphen. The notation is too varied for a reliable format, so no regexp is given. - Personal data (PII): no - Categories: Publishing and print (publishing) - Countries: Russian Federation (RU) - Languages: Russian (ru) - Classification: categorical ## Examples - `88я2` — Big psychological dictionary - `86.37-2` — The Bible - `Т3(2Г)0-6я43` — The past through the prism of the present (Wikidata example) - `72 Д63` — Index 72 and the author mark Д63 (The Magic of Reality) ## Mappings - wikidata: `P8391` ## Translations - ru: Индекс ББК (библиотечно-библиографическая классификация): Индекс национальной библиотечной классификации России: цифры, буквы кириллицы и знаки типовых делений, например 88я2.
