Transbook aims to increase competitivity and widen the audience in the children's book industry on a European scale (authors, illustrators, translators, publishers, booksellers, librarians). This will be achieved  by accompanying the children's book industry through the digital transition and strengthening its international scope. This cooperative project is a pioneering network initiative that will create bonds between several cultural sectors, including; books, cinema, television, video games and design. Although it affects all sectors, a special emphasis will be put on the most fragile of them - small publishers, young creators and independent booksellers.The action plan is structured into three axes: • Axis 1: Encourage the key players  to invest the new business models and modes of creation (conference From Paper to Screen and rights market, MÏCE) • Axis 2: Galvanize creators' careers (meetings, masterclass, mobility program, ambassadors) • Axis 3: Encourage the use of innovative mediation systems (meeting with programmers, mediators seminary, exhibition). These axes are coordinated in an interdisciplinary way on Transbook.org, which also ensures the dissemination and communication of the project.Originating from 7 European countries, the partners are all structures that organise fairs and festivals and are used to gathering the key players within their sector to participate (authors, translators, publishers, booksellers and librarians). They therefore have a privileged position with the capacity to legitimately instigate this interdisciplinary program. Their various professional networks are key assets for the international aspect of the project.Throughout the project, special care will be given to disseminate knowledge way beyond the professionals who will attend the events. In this view, Transbook.org is designed to offer a considerable amount of original information and will become a useful reference database.
