Main Changes

• "Search": Use this for standard queries.
• "Advanced Search": Use this to query less frequently used search fields and to construct boolean expressions.
• "Command Search": This query form gives you full control over the database by using a powerfull query command language.
• "Citation Checker": Conveniently and quickly check your article literature references and get persistent links to individual Zentralblatt MATH database items.

Classification: combined classification and search

• Browse MSC2000 classification by topic or search for classifications whose definitions contain certain words.
• Your chosen classification code is inserted into a query form, with an indication how many documents match this code. You may then further restrict your search.

• Browse by abbreviation
• Search by keyword
• Search by ISSN
• Get the full list of serials and journals covered by Zentralblatt MATH
• Your chosen journal (ISSN number) is inserted into a query form.

Diacritical characters now appear in HTML output whenever possible. However, the full set of special characters is only available in DVI, PS, and PDF output.

Enhanced functionality of PDF output: Better screen readability, full Zentralblatt MATH linking mechanisms embedded.

New numbering scheme

New numbering scheme for preliminary entries:
Entries that are currently in the editorial process of Zentralblatt MATH but not in final form appear with an eight digit number, prefixed by "pre". As soon as these entries are finally published, the receive their final Zbl no. However, they are still accessible via the preliminary number.

All final entries have a Zbl number of the form VVVV.CCNNN where VVVV is the number of the printed Zentralblatt MATH volume where this item has appeared, CC is the main classification section code, and NNN is a number.

Direct links

Direct links to individual Zentralblatt MATH items can be established once you know their (preliminary) Zbl number:

Abstracts might contain active links to JFM ("Jahrbuch über die Fortschritte der Mathematik") for literature published before 1931. The JFM-numbers refer to abstracts and reviews in ERAM, Electronic Research Archive for Mathematics (1868-1931).
