Virtual library
„Digital libraries– electronic media in various forms :
Electronic library– library services shared in a distributed
environment (consortia) : Virtual library– holdings and services integrated in
uniform interface with enhanced value“
Endres, Fellner : Digitale Bibliotheken, dpunkt-Verlag (2000)

Situation at ETHZ
• ETHZ executive board decision (1999) : One print subscription only
• Cooperative financing of e-journals bylibraries
• 6000 e-journals• 2000 chemistry/biology/ physics/
pharmacy e-journals

User Survey in ChemistryDepartment
• Reason : Information sourcesincreasingly available at workbench
• Use of electronic scientific information– Demography: PhD students, assistants,
professors, scientific employees– 17 question clusters– 178 questionnaires returned (34%)– Around Christmas 2001

Strategy
Improve quality of information use by
• Support, training, education– electronic media and tools
• E-services– subject specific– personalization– portal functions
M. Brändle, E. Zass, 226th ACS National Meeting, 8.9.03 10
E-education tools• German project
„ Vernetztes Studium - Chemie“ (Networks for Chemistry Education)
• BMBF/FIZ Chemie• Basic Syllabus :
„Würzburger Modell“, Eurobachelor• 19 Groups: 16 DE; 2 UK, 1 CH• 9 Subject areas:
Chemical information/chemoinformatics(Prof. J. Gasteiger, Univ. Erlangen)
M. Brändle, E. Zass, 226th ACS National Meeting, 8.9.03 11
„Vernetztes Studium - Chemie“• Modular (VLU)• XML• Meta information
• Chemicalinformation– ~3000 objects:
text, images, links, multimedia
– Basic, source, problem modules
M. Brändle, E. Zass, 226th ACS National Meeting, 8.9.03 12
E-services : Architecture of a virtual library
• Dynamic content• Personalization• Linking and interfacing• Meta information• Federated searching
M. Brändle, E. Zass, 226th ACS National Meeting, 8.9.03 13
Dynamic content• Must be input once into databases :
Formalization• Managed independently• Control of workflow :
Publication - Expiration - Archive• Selection, classification :
Same data, different views• Consistent usability• Additional functionality for users :
Personalization, rating
M. Brändle, E. Zass, 226th ACS National Meeting, 8.9.03 14
Dynamic content : Architecture
• Library informationsystems as databack-end
• e.g., CLICAPS– Standard library
functions– Added functions
M. Brändle, E. Zass, 226th ACS National Meeting, 8.9.03 15
Dynamic content : Example e-journals
M. Brändle, E. Zass, 226th ACS National Meeting, 8.9.03 16
Personalization• e.g., Current awareness of e-journals• Outlook:
Databases, search profiles, links, e-books, news
M. Brändle, E. Zass, 226th ACS National Meeting, 8.9.03 17
Linking and interfacesReference linking• Important part of
virtual library• e.g., Vertical
linking2o - 1o lit.
• Chemistry : also data linking(XML, CML)
M. Brändle, E. Zass, 226th ACS National Meeting, 8.9.03 18
Meta information : Classification• Visualization :
StarTree Java Applet (Inxight Software Inc.)
• Both printedand online media classified
M. Brändle, E. Zass, 226th ACS National Meeting, 8.9.03 19
Meta information (2)• Creation of classes• Prototype : General
purpose thesaurus– Polyhierarchic– Link lists– Standard study texts– Databases– Properties– Profile generation
(presently ~500 e-books in CLICAPS)
