Organisational Structure • leaders of the whole project: • Elmar Mittler (SUB Göttingen) • Bernd Wegner (TU Berlin) • additional partner: • Zentralblatt für Mathematik (FIZ Karlsruhe) • editors of the database: • Keith Dennis (Cornell University) • Bernd Wegner (TU Berlin) • supervised by EMS • editorial support from more than 150 volunteers
What is ERAM? • bibliographic metadata & digitization of fulltext for classical mathematical literature • JFM: Jahrbuch über die Fortschritte der Mathematik • capture the content of the JFM in a database • scan selected items covered by the JFM for storage in an electronic archive • extend the content of the archive by other selection methods and provides links to the database • funded by DFG (German Research Foundation)
ERAM ideas • longevity of research results in mathematics • better availability in electronic archives • access through literature databases • preservation of documents which suffer from the deterioration of the paper as consequence of age
History of JFM • was founded 1868 by the mathematicians Carl Ohrtmann and Felix Müller • their intention was ...to provide a tool for those, who are not able to follow all publications on the comprehensive field of mathematics, and to gain a general overview about the development of the science ...help the active scientist to find out known facts • JFM appeared in 68 issues from 1868 until 1942
History of JFM cont. • total amount of 200.000 units • reviews of all mathematical publications from that period • for every year one volume • edited by Prussian Academy of Science • published by de Gruyter
Why JFM • today some original publications are still valuable sources for mathematical research • but not many researchers, libraries of universities, high schools and research institutes have access to the complete JFM • to create a database of the JFM and a digital archive of the most important publications of this time
JFM Database • digitization of the printed issues of the JFM • enrichment of the original data by mathematicians and librarians: • classification regarding the Mathematical Subject Classification 2000 • description by English keywords • evaluation and selection for the digital archive • supplements to the bibliographic data (e.g. in different forms of the name of the authors or various types of journal titles)
JFM Digital Archive • scanning the relevant publications (up to 20% of all publications) • linking to the scanned documents starting from the JFM database • presentation and long-time-storage in a document-management system
Input Activities • development of an appropriate field structure • keyboarding of the content using the TEX-code (formula display) • raw division according subjects • distribution to librarians for standardisation • distribution to voluntary experts for enhancements
Who digitizes? • GDZ: Göttinger DigitalisierungsZentrum - The Center for Retrospective Digitization, Göttingen State and University Library (Germany) • is part of an initiative to build a German digital research library • coordinate national efforts towards standardization in various fields (e.g. digital conversion, online access, bibliographic description) • financial support from the State Ministry for Science and Culture
Standardisation & Enhancements • author identification • source identification • references to library holdings • English title translations • classification according to MSC • assignment of keywords • comments on the scientific impact of the items • ranking for scanning
JFM Database: Search Facilities • Boolean search • Menu driven search • Full downloading • BIBTEX export • Different display modes • Links to the archive • Document delivery • Author • Title • MSC 2000 • Basic Index • Source • Language • Document type
GDZ Search • also possible to search directly in the GDZ Document Server: • http://www-gdz.sub.uni-goettingen.de/agora/html/docs/ • define an Advanced Search • Document Types = Journal • Digital Collections = Mathematica • search in one periodical (e.g. Mathematische Annalen) in all volumes with Table of Contents for each volume
The Archive - Contents • articles recommended by the JFM-experts • handbooks and encyclopaedias (out of print) • dissertations • selected monographs (out of print) • complete sets of back volumes of journals (Mathematische Annalen, Math. Zeitschrift) • print-only back volumes of currently dual journals (Beiträge zur Algebra und Geometrie et al.)
Time Schedule • end of database input: June 2001 • amount of data in the database: raw data 78%, enhanced data 30% • raw and edited data freely accessible in the web • enhancement of data - living project • scanning of documents immediately according to the licenses given by editors • soliciting for new journals to participate - open project
Future Actions • combine the content with other digital archives (JSTOR, DIEPER-partners etc., Cornell) to a distributed digital archive in mathematics • negotiate a license to digitise a selection of Russian mathematical journals • develop an automatic indexing system to be applied to the documents not handled by voluntary experts • extend the offer of searchable text via OCR
