Zentralblatt MATH (German: central math journal) is a service providing reviews and abstracts for articles in pure and applied mathematics, published by Springer Science+Business Media. It is a major international reviewing services which cover the entire field of mathematics. It uses the Mathematics Subject Classification codes for organising their reviews by topic. The Zentralblatt MATH abstracting service provides reviews (brief accounts of contents) of current articles, conference papers, books and other publications in mathematics, its applications, and related areas. The reviews are predominantly in English, with occasional entries in German and French. Reviewers are volunteers invited by the editors based on their published work or a recommendation by an existing reviewer. The service was founded in 1931 by Otto Neugebauer as Zentralblatt für Mathematik und ihre Grenzgebiete. The electronic form was provided under the name INKAMATH (acronym for Information System KarlsruheDatabase on Mathematics) since at least 1980. The name was later shortened to Zentralblatt MATH. Nowadays, Zentralblatt MATH is provided both over the Web and in printed form. The service reviews more than 2,300 journals and serials worldwide, as well as books and conference proceedings. Zentralblatt MATH is now edited by the European Mathematical Society, FIZ Karlsruhe, and the Heidelberg Academy of Sciences. The Zentralblatt database also incorporates the 200,000 entries of the earlier similar publication Jahrbuch über die Fortschritte der Mathematik (JFM) 18681942, added in 2003. Access is by subscription. Currently, the first three records in a search are provided for free without a subscription. Historical remarks In the late 1930's the Zentralblatt MATH began rejecting some Jewish reviewers and a number of reviewers in England and United States resigned in protest.[1] Some of them helped start a competing publication "The Mathematical Reviews".
