An electronic library or digital library - is a virtual organisation which, by using infocommunication technologies, makes texts of great quantity accessible for readers in a systematic form, like ordinary libraries. (
Its important novelty is that a direct connection can be built between the catalogue and certain elements of the file (the documents and the metadata describing them), which makes the information accessible in an easier and more comfortable way.
As electronic libraries are available for masses of people without any restrictions (financial, temporal etc.), they have become the honoured means of informal learning. (Hungarian Virtual Encyclopaedia)
