Goettingen Digitization Centre

Department of the Goettingen State and University Library

Founded in 1997 and for 4 years funded by the German Research Foundation (Deutsche Forschungsgemeinschaft, DFG)

National and international support and service-centre for (retro-)digitization

4

The Goettingen Digitization Centre

Co-ordinating national efforts towards standardization

Testing and providing tools and techniques for image capture and text conversion, bibliographic description, document management, and the provision of online access to digital collections

Building up professional responsibility concerning the whole digitization process (methodical and technical) within the library department

5

Main activities of the GDZ

• Make available printed material in a user friendly way via WWW

• Rare and unique records, e.g. rara, incunabula and manuscripts

• Mass-digitization, e.g. science journals

• Service for projects, academic institutions and publishers: production of digital images

• Integration of special research aspects

• About 2 million pages on the GDZ server available

6

Bibliographical and Structural Metadata

• Format: RDF/XML (Ressource Description Framework/eXtensible Markup Language)

• Migration to METS (Metadata and Transmission Standard): more detailed and more flexible

• Storage and access with document-management-system

• Standards • Interoperability• Long term preservation

7

Online Library Catalogue

Necessary for acceptance of the digital library

For the GDZ - first step of the whole digitization process

PICA-production-number as identifier of the digitized work

Direct link: GBV union catalogue or local OPAC to the GDZ-document-server via http-protocol

8

TIFF-Header: allows exact identification of each image – even if folder structures are destroyed

Bibliographical Metadata: for presentation and retrieval PPN = PicaProduction Number = Identifier

9

Structural Metadata

Aim is to offer an electronic table of contents with direct links to the digitized works and a user-friendly navigation

Early Zoological Literature Online

Cooperation with the Institute for Zoology at Goettingen University, Prof. Rainer Willmann

Fulltext digitization of Carl von Linnés base reference work of zoological nomenclature

Linking with descriptions and literature he quoted

Building up a zoological database, important for the recent research in the field of

biodiversity
