During the 1996 CENL meeting in Lisbon, Portugal, it was decided that Gabriel would become an official CENL website in January 1997. Gabriel was maintained by the national library in the Netherlands, and mirrored by four other national libraries, in United Kingdom, Finland, Germany, and Slovenia.

Eight years later, in summer 2005, Gabriel merged with the European Library's website, as a common portal for the 43 national libraries in Europe. In March 2006, the European Commission launched the project of a European digital library, after a “call for ideas” from September to December 2005. This European digital library – named Europeana - opened its "virtual" doors in November 2008, with a crash from the server within 24 hours, followed by an experimental period with part of the collections.

In 1998, eight years before launching Europeana, the European Commission was running a Library Program(me) for public libraries, that aimed "to help increase the ready availability of library resources across Europe, and to facilitate their interconnection with the information and communications infrastructure. Its two main orientations will be the development of advanced systems to facilitate user access to library resources, and the interconnection of libraries with other libraries and the developing 'information highway'. Validation tests will be accompanied by measures to promote standards, disseminate results, and raise the awareness of library staff about the possibilities afforded by telematics systems."

In December 1998, according to a document posted on the website of the European Commission, 1,000 public libraries from 26 European countries had their own websites, that ranged from one webpage - with a postal address and opening hours - to several webpages - with full access to the library's OPAC (Online Public Access Catalog) and a variety of services. The leading countries were Finland (247 libraries), Sweden (132 libraries), United Kingdom (112 libraries), Denmark (107 libraries), Germany (102 libraries), Netherlands (72 libraries), Lithuania (51 libraries), Spain (56 libraries), and Norway (45 libraries). Newcomers were the Czech Republic (29 libraries) and Portugal (3 libraries). Russia had a common website for 26 public reference libraries.

# A definition

What exactly is a digital library? The Universal Library Project, hosted by Carnegie Mellon University, defined it in 1998 as "a digital library of digital documents, artifacts, and records. The advantage of having library material available in digital form is threefold: (1) the content occupies less space and can be replicated and made secure electronically; (2) the content can be made immediately available over the internet to anyone, anywhere; and (3) search for content can be automated. The promise of the digital library is the promise of great cost reductions while providing great increases in archive availability and accessibility. (…) There are literally thousands of digital library initiatives of a great many varieties going on in the world today. Digital libraries are being formed of scholarly works, archives of historical figures and events, corporate and governmental records, museum collections and religious collections. Some take the form of scanning and putting documents to the World Wide Web. Still other digital libraries are formed of digitizing paintings, films and music. Work even exists in 3D reconstructive digitization that permits a digital deconstruction, storage, transmission, and reconstruction of solid object."

Since the mid-1990s, libraries were studying how to store an enormous amount of data and make it available on the internet through a reliable search engine. Library 2000 was a project run between 1995 and 1998 by the MIT Laboratory for Computer Science (MIT: Massachusetts Institute of Technology) to explore the implications of large scale online storage, using the digital library of the future as an example. It developed a prototype using the technology and system configurations expected to be economically feasible in 2000.

Another project was the Digital Library Initiative, supported by grants from NSF (National Science Foundation), DARPA (Defense Advanced Research Projects Agency) and NASA (National Aeronautics and Space Administration). As mentioned on its website in 1998: "The Initiative's focus is to dramatically advance the means to collect, store, and organize information in digital forms, and make it available for searching, retrieval, and processing via communication networks - all in user-friendly ways."

The British Library was a pioneer in Europe. Brian Lang, chief executive of the library, explained on its website in 1998: "We do not envisage an exclusively digital library. We are aware that some people feel that digital materials will predominate in libraries of the future. Others anticipate that the impact will be slight. In the context of the British Library, printed books, manuscripts, maps, music, sound recordings and all the other existing materials in the collection will always retain their central importance, and we are committed to continuing to provide, and to improve, access to these in our reading rooms. The importance of digital materials will, however, increase. We recognize that network infrastructure is at present most strongly developed in the higher education sector, but there are signs that similar facilities will also be available elsewhere, particularly in the industrial and commercial sector, and for public libraries. Our vision of network access encompasses all these."
