zbMATH Open (formerly known as Zentralblatt MATH) is a pioneering abstracting and reviewing service in pure and applied mathematics. It is edited by the European Mathematical Society (EMS), the Heidelberg Academy of Sciences and Humanities, and FIZ Karlsruhe. Since January 2021, zbMATH Open has been available as an open access service, becoming a crucial hub in the global network of mathematics information.

Currently, zbMATH Open contains around 4. 4 million bibliographic entries with reviews or abstracts drawn from more than 3,000 journals and book series, and some 190,000 books. The service provides easy access to bibliographic data, reviews, and abstracts from all areas of pure mathematics, as well as applications and covers all available published and peer-reviewed articles, books, conference proceedings, and other publication formats.

The extensive coverage starts in the 18th century, and the entries are classified according to the Mathematics Subject Classification Scheme (MSC 2020). With more than one million author profiles and links to full texts, zbMATH Open is a valuable resource for researchers, editors, and publishers in the field of mathematics. It is a comprehensive and accessible platform for accessing mathematical literature, reviews, and abstracts
