- via 1 central multi-lingual web interface

- (= portal)

What is The European Library?

2.1 Introduction to The European Library

www.TheEuropeanLibrary.org

Background Origin in 2001: TELproject: 2.5y feasibility study funded

by EU and led by The British Library Intended to create operational service from start, so

business plan was part of TELproject

The European Library is live since 17 March 2005 (beta)

Currently owned by CENL, funded by the national libraries (NOT EU)

Development + maintenance by The European Library Office (Netherlands – 9 FTE)


Two types of participants

Full Participants : libraries whose catalogues and digital collections are included in The European Library portal (23)

Basic Participants : catalogues and digital collections not yet included (24)


Current + future Full Participants Now : 250+ collections from 23 national libraries:

Austria, UK, Croatia, Denmark, Estonia, Finland, France, Germany, Italy(2x), Latvia, Netherlands, Portugal, Serbia, Slovenia, Switzerland, Poland, Cyprus, Malta, Lithuania, Hungary, Czech Republic, Slovakia

End 2007 : 330 collections from 34 librariesSpain, Liechtenstein, Luxembourg, Norway, Sweden, Greece, Iceland, Ireland, Belgium, Bulgaria & Roumenia

Mid 2009 : 400 collections from 44 librariesRussia (2x), former Sovjet republics, Albania, Bosnia…..


What’s Good about The European LibraryFor end-users

Have integrated access to catalogues & digital collections of national libraries of Europe

Quality-controlled deep web resources 250+ collections, 2.0M digital objects and 50M

metadata records

For the national libraries International showcase for collections Wider access to their collections & content Combined political mass greater marketing

and negotiation power. Platform for collaboration


2.1 Introduction


A. Access protocols

B. Metadata


D. Multi-linguality


The European Library = hybrid portal = federated search tool

Overall goal of The European Library = COLLABORATION Low implementation barrier for libraries is key!!

Different libraries demand different access protocols to access their collections

TEL infrastructure uses 4 protocols : OAI-PMH, Z39.50, SRU, OpenURL

The European Library portal queries 1 central index (90 harvested collections, OAI-PMH)

160 remote databases (Z39.50 & SRU)

2.2.A Access protocols in The European Library

Techniques / protocols used (I)

1. OAI-PMH (Open Archives Initiative Protocol for Metadata Harvesting)

OAI enabled collections have their metadata harvested, indexed and stored in TEL central index

Queries in these collections are queries in TEL central index

2.2.A Access protocols in The European Library

2. SRU (Search Retrieve via Url)SRU enabled collections are queried on-the-fly using this

protocol Direct communication with TEL-portal

3. Z39.50Z39.50 enabled collections are queried on-the-fly via a

Z39.50/SRU gateway

Z39.50/SRU gateway = translator (housed on TEL server)• Translates SRU requests to Z39.50 session vv.• Translates TEL portal search language (CQL) into

search language of Z39.50 target. • Converts record format of Z39.50 target into TEL

metadata format• Does character set conversions (Unicode)

European Digital Library =

- yet to be built - pan-European - multi-lingual portal - giving access to

digital cultural heritage

- from European libraries AND museums & archives

3. Ingredients for a successful European Digital Library

The European Library =

- operational - pan-European - multi-lingual portal - giving access to

digital cultural heritage

- from European libraries only

December 2004 : Google announces its Google Print initiative (digitse 4 major US libraries + Oxford UK)

January 2005: comments by Jean-Noël Jeanneney (president BnF) : Anglo-American dominance

Large press coverage: “Europe’s cultural war with Google”

French call for safeguarding the European cultural heritage: Backing from the leaders of six countries and 24 national libraries (CENL)

EU 2005 : “Creation of a European Digital Library is a strategic priority“

Short historical context


EU 2006 : “The European Library is a good starting point for a European Digital Library”

Timeline & Vision of the EU


Towards a European Digital Library

Why is The European Library a good starting point for a European Digital Library?

The European Library already has already created

Operational technological platform (portal)

Based on common open standards for metadata & access

Firm cooperative organisational framework (CENL - 20 years)


BUT…

A successful European Digital Library needs more ingredients

……

Look at 7 of them…. challenges


Challenge 1 Mass-digitisation of as many materials as possible

Challenge 2Long-time digital preservation of these digitised materials

3. Ingredients for a successful European Digital LibraryChallenges to tackle (1,2)

Mass-digitisation & preservation

Problem Only 4% of content in The European Library are digital objects Even lower %-tage is digitally preserved Solutions Mass-digitisation & preservation programmes Europe-wide

network of centres of competence

Hurdles1. Organisational : create synergies, avoid duplication of effort, create

public-private collaboration. 2. Content selection : choose from 1000s kms of printed materials; Ms

hours of film3. Technical : lower costs for digitisation & preservation while

maintaining a high quality.4. Legal : deal with the copyright issues


Challenge 3More partners, esp. museums, archives, AV

Challenge 4Multilingual search & retrieval facilities Searching in German, finding texts in Spanish Start with controlled vocabularies (subject headings), uncontrolled vocabularies/free texts will be next step.

Challenge 5OAI + central index : prefer OAI-PMH + central index over Z39.50 or SRU remote collections- speed- sorting- ranking - de-duplication- virtual collections

3. Ingredients for a successful European Digital LibraryChallenges to tackle (3,4,5)

Challenge 6

Organisational modelsOwnership / governanceFunding modelsSustainability

Challenge 7

Copyright issues, publishers

All of these challenges are addressed in a series of EU co-funded projects 2007-2011


Summary

Common and open standards for access and interoperability are essential for a European Digital Library

The European Library is the forerunner

Building a European Digital Library is a much a political & social game as it is a technological

Willingness to collaborate is key!!
