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)

M. Brändle, E. Zass, 226th ACS National Meeting, 8.9.03 3

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/

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)
