Zentralblatt MATH (zbMATH) is the world’s most comprehensive and longest running abstracting and reviewing service in pure and applied mathematics. The zbMATH database contains more than 3 million bibliographic entries with reviews or abstracts currently drawn from more than 3,000 journals and serials, and 170,000 books. The coverage starts in 1826 and is complete from 1868 to the present by the integration of the “Jahrbuch über die Fortschritte der Mathematik” database.
"Журнальный зал" (ЖЗ) is a nonprofit literary web-project, representing the activities of Russian literary and humanities journals published in Russia and abroad.
