The chapter gives an overview of developments in international publishing and the global book market. Book publishing has moved from being international to a global system where the number of titles, publishers, and overall economy is constantly increasing. International publishing is marked by conglomeratization and polarization where large and small publishers operate on an unequal market. The size of a publishing house effects economy, visibility and attention and books published by the major international publishers will have a much wider dissemination and sales than a small company. On the other hand, most translated books are published on modest scale, by small or micro-publishers. The chapter also frames a digitized market that has pushed a multinational corporate literature in combination of a digital platform economy of self-publishing. In a global but unequal literary space of world literature circulation follows established power structures and postcolonial trajectories.
