1. Zentralblatt MATH Searching for Mathematics with Zentralblatt MATH Overview and Outlook Bernd Wegner, Heinz Kröger Zentralblatt MATH, FIZ Karlsruhe Mathematisches Institut, TU Berlin

2. Overview  The reference database Zentralblatt MATH  The LIMES production system  Zentralblatt search facilities  Zentralblatt linking facilities

3. Part 1  The reference database Zentralblatt MATH

4. Zentralblatt MATH Editorial Council  European Mathematical Society  FIZ Karlsruhe  Heidelberger Akademie der Wissenschaften  Editor - in - Chief  Co-operational units  Publisher: Springer-Verlag

5. The Role of Reviewing Services  Documentation and evaluation of the mathematical literature world-wide  Provision of an easily accessible, searchable database  Portal site to published articles and books  Access facility to document delivery  Tools for preparation of bibliographies and reference linking  Identification facility for mathematical publications  Let us look at how Zentralblatt MATH fits in here:

6. Zentralblatt MATH Aims  Comprehensive information on mathematical publications  Bibliographic precision  Reviews given by external reviewers  Classification according to subjects, additional keywords for database retrieval  Links to other electronic sources in Math  Convenient search menus for different levels of expertise

7. Zentralblatt MATH Scope  Pure and applied mathematics  Mathematical physics  Theoretical computer science  Theoretical mechanics  Operations research  Financial mathematics  Statistics, mathematical biology  Systems and control theory  Coding and Communication

8. Zentralblatt MATH Figures  Total number of papers reviewed in Zentralblatt MATH since 1931 >2.200.000  Number of papers reviewed in JfM (1868 – 1930) 80.000  Number of reviewers > 9.000  Number of Journals covered > 2.300

9. Part 2  The LIMES production system

10. LIMES Large Infrastructure in Mathematics - Enhanced Services  Fifth Framework Programme of the EU "Access to Research Infrastructures ”  EU-funding: April 2000 - March 2004  Scientific Directors:  Rolf Jeltsch, ex-President EMS  Bernd Wegner, Editor-in-Chief Zbl MATH  Coordinator:  Michael Jost, FIZ Karlsruhe, Berlin Dept.

11. LIMES Partners FIZ Karlsruhe, Coordinator, DE Cellule MathDoc, FR Eidetica, NL SIBA, University of Lecce, IT Tech. Knowledge Centre & Library of Denmark, DK University of Santiago de Compostela, ES Hellenic Mathematical Society, GR Technical University Berlin, DE European Mathematical Society, EU

12. LIMES Distributed Input  Development of a new input and database production system (in operation since 01.04.2004)  Capable for accepting input from distributed partners  Allowing for corrections and modifications from distributed sites  Implementing shared responsibilities  Portable to other services and disciplines like  Education in mathematics  Mathematical Logics  Computer Science  Physics

13. LIMES Quality of Data and Retrieval  New models, techniques and tools for the enhancement of data and a more sophisticated retrieval  Author and Source identification  Development of new and enhanced retrieval features for the database engine  Support for distributed servers:  multilingual interfaces  access control management  update procedures

14. LIMES Electronic Editorial Units  Arrange the workflow using electronic means as much as possible  Integrated access to shared resources (reviewer database)  Apply artificial intelligence concepts for semi- automatic indexing  Integrate available metadata automatically  Two prototypes  NAIS developed by SIBA in Lecce  TEQUILA developed by DTV in Copenhagen

15. Part 3  Zentralblatt search facilities

16. Search menus  We offer three menus for different levels of expertise, and a citation checker  Standard search form  Advanced search form  Command mode search form  Citation checker

17. Search fields  Author  Title  Basic Index  Classification  Source  Reviewer  Zentralblatt Number  Language  Document Type

18. Database tools  Journals Database  MSC (Classification Scheme)  Reviewer Database (LIMES internal)  Lookup system (Citation search form)

19. Part 4  Zentralblatt MATH linking facilities

20. Links from ZBL  Links to items of the bibliographic information (you may, e.g. click on an author, a reviewer, classification code or citations to generate a new search)  Links to electronic resources  Links to digital archives

21. Navigation with ZBL  Reference links  Provision of metadata for digitization projects  Interaction with Encyclopaedias, Handbooks und Bibliographies (to be realized)

22. Integration in Digitizing und Archiving Projects  Integration of Zentralblatt MATH (and JFM) into the access and navigation structures of  WDML (World Digital Mathematics Library) With its European branch DML-EU  ERAM (FDM project)  EMANI (Electronic Mathematics Archiving Network Initiative)  Look-up tools for the generation of reference links from digitized offers  Recommendation of the WDML planning group DML-EU

23. Integration in the production and promotion of RusDML  RusDML – core archive of digitized Russian journals in mathematics  journalwise provision of metadata of Zentralblatt MATH and of FDM  Implementation of a fast access to the journals  Range of articles covered is from 1868 to present  Access to the reviews also for users with minor knowledge of the Russian language  Linking of the database with the digitized items  Permanent access to the archive in additon to the Russian-British OPAC

24. Linking to free offers of full texts in EMIS  Electronic library within European Mathematical Information Service  Host for free full text offers of core journals in mathematics  More than 60 journals  More than 10.000 articles  Immediate access to the journals via Zentralblatt MATH  Linking between full texts and database entries  Links from the bibliographies to database entries  Adaption of the production of metadata to the needs of Zentralblatt MATH – direct adoption

25. Cooperations of Zentralblatt MATH with systems for full text supply  Generating links from the database entries to document delivery services – direct transfer of bibliographical data  TIB Hannover, SUB Göttingen, JASON, SIBA Lecce, REBIUN (Spain), HEAL-Link (Greece)  Delivery terms are determined by the vendor.  Integration of the database into local systems, which offer their service only to local customers.  Combined agreements for database access and full text supply in developing countries – CubaMATH, Southern Africa  Integration into projects for the integrated access to electronis offers (EULER, EASE and others.)  Links to Publishers.
