Authors royalties, half billion euros paid by French publishers a year, are a key issue for the book publishing business. They tend to be squeezed because the level of royalties is the only parameter easily manageable by publishers. These are at risk of being outflanked because the authors whose part of the editing process has increased due to technical evolutions, will deal without them. Nevertheless, the book’s status remains a key asset for publishers. Besides, the growth of the returns coming through collective institutions is linked to the adaptation of these mechanisms.
