Public libraries, which are deeply rooted in the European history of cities, communities and rural lives are undergoing a profound change (crisis) due to the "dematerialisation" of the book, the development of the Web, the rapidly evolving information technologies. In many communities around Europe libraries are still the only place where a person, regardless of education or skill level, can have access to information; for the economic crisis, libraries services have been severely hit because of budgetary cuts. In accordance with the European Commission recommendations (Green Paper of 27 April 2010 – Unlocking the potential of cultural and creative industries” (COM(2010) 183), libraries can revitalize and renew matching cultural and creative industries, initiating a cross fertilisation process. The general objectives of our project are to set up transnational models to develop and test innovative, sustainable and effective solutions for public libraries, facing the information society challenges, for a better participation of all social groups, actors and users in the design and delivery of the services, starting from the local community needs and in partnership with cultural and creative industries. Design thinking processes, that have been successfully exploited in other contests, can support libraries facing these challenges.
