Subject classification schemes in mathematics MSC – Mathematics Subject Classification for the bibliographic databases – MathSci, edited by the American Mathematical Society – Zentralblatt MATH, edited by the European Mathematical Society, the Fachinformationszentrum (FIZ) Karlsruhe, Germany and other Editorial Units all over Europe ZDM – Zentralblatt für Didaktik der Mathematik Classification Scheme for the bibliographic database – MathDI, edited by the European Mathematical Society, FIZ Karlsruhe, and Zentrum für Didaktik der Mathematik at Karlsruhe University, in cooperation with Math Doc Cell (France)

Subject classification schemes in computing and physics CCS – Computing Classification System developed by the Association for Computing Machinery PACS Physics and Astronomy Classification Scheme developed by the American Institute of Physics INSPEC Classification – Section A: Physics & Astronomy – Section B: Electrical & Electronic Engineering – Section C: Computer & Control – Section D: Information Technology

The common structure of subject classification schemes Categories: Codes and Descriptions Main ordering relation: mono- or multihierarchical Cross-references Versions

Classification schemes: from structure to browsing Browsing for search or data entry in metadata repositories Organizing knowledge in lexical databases, dictionaries, encyclopedias, surveys, digital libraries

The Scientific Classification Page Sections: The Mathematics Classification Page Mathematics Subject Classification MSC and Dewey Decimal Classification DDC Relating Scientific Subject Classifications Display modes: Simple frame Double view KWIC lists of descriptions

The Mathematics Classification Page MSC 2000 in: simple frame presentation – English text – Italian translation – interleaved English and Italian texts – with marks of changes from MSC 1991 – with links to subject specific pages of relevant Websites double view presentation – English text

Relating Scientific Subject Classifications linked categories in double view presentation of: ACM CCS (1998) and MSC 2000 separate KWIC lists of descriptions of: MSC 2000 PACS 2001 ACM CCS (1998) – English text – English text with appended Italian text a combined KWIC list of descriptions of: MSC 2000 and PACS 2001 MSC 2000 and ACM CCS (1998)

Towards the OAI framework The need of quick research communication vs. the slow formal process of journal submission Dissemination methods: from paper documents to the Internet

Searching through personal homepages and small archives The fragmented world of ftp sites and web pages Citeseer-Researchindex: one solution...

E-print communication: tools and networking strategies small specialized archives arXiv: a potentially catch-all archive single or networked institutional archives (NCSTRL, ERCIM Technical Reference Digital Library) distributed networks connected by some interoperability protocol (RePEc, ReLIS) umbrella servers (MPRESS) servers connected to groups of journals servers sponsored by commercial publishers

The Open Archives Initiative Fundamental concepts and tools: Data providers Service providers – Search facilities for end users – Reference linking Metadata harvesting – The OAI Protocol for Metadata Harvesting

OAI compatible refereed self-archives: the EPrints software EPrints developed at the University of Southampton (UK). Functions – Searching in the archive – Browsing the archive – User registration – Depositing an e-print – Processing a submission – Exporting metadata for OAI-compliant harvesting

Conclusions The OAI framework can be integrated by archives and service providers with enriched browsing functionalities Hypertextual displays of a full network of bridges among specific subject areas can guide advanced communication activities inside mathematics and between the disciplines that live and develop with mathematics
