The word “digital library” is on everybody’s lips nowadays and it is used to describe a wide range of products, services and projects. Actually, the word would refer to anything that involves the creation and distribution of any kind of digital information. The digital library is an always different assemblage of one or more collections of digital objects and these collections are called “repositories”. It is the place where the collections and the digital objects are presented and integrated through metadata. Usually, a digital library has two faces: the first one is for the staff while the second is for the remote user. A digital library can be described, modelled, drawn, implemented, used and evaluated.
