The Global Trade and Standards Organization for Digital Publishing

IDPF develops and maintains, EPUB®, the next-generation open standard for accessible, interoperable digital publications, learning content, and other electronic documents. IDPF also provides a forum that fosters enhanced communication between all stakeholders in the global digital publishing industry. 


    The IDPF condemns the outrageous and tragic attacks in Paris which have taken the lives of at least two members of the French publishing industry. We stand in solidarity with our many friends, colleagues and members in France. Access to information and knowledge is the single most powerful tool available to promote world peace. IDPF supports this wholeheartedly through its mission to increase access to information and content on a global basis by fostering open standards. We can not and will not let terrorism prevent the advancement of global knowledge, peace and prosperity so we will continue to promote these ends as one element of the fight against barbarism. The IDPF grieves for all the victims and we extend our sincere condolences to their families.
