The technological interoperability of digital libraries must be rethought in order to adapt to new uses and networks. Informative digital environments aimed at responding to heritage, cultural, scientific or commercial demands have taken over the global cyberspace and have redesigned the techno-informative landscape of the Web. However, while the technological models demonstrate their effectiveness and explain to a large extent the creation of digital libraries, archives and deposits, the subjacent concept of uses continues to cause debate. The information technologies used by heterogeneous digital libraries enable a technical interoperability of content. This is not enough to allow the adhesion of a public connected to very different information profiles and techniques. This book explores the avenues of a user-orientated interoperability where the questions of consultation interfaces and content description processes are studied.

The digital libraries emerging from "information societies" no longer concern only digital technodocumentary devices that are patrimonial, cultural or scientific. Social networks and high-audience merchant sites share the same technologies, heterogeneous digital resources, offer identical user experience (UX) capabilities, and are born within the same communities of designers and engineers. These technology-induced recoveries nourish a usage fantasy that irrigates a transformation movement of innovation where use and user occupy a central place. The evolution of digital libraries does not constitute a disjointed set of singular innovations. They are the result of an innovation movement that gives them a specific dynamic and produces two major effects: empowering users and increasing their number. This book highlights and study that the combination of these effects is likely to have a positive impact not only from an economic point of view but more broadly from a social point of view.
