Throughout the nineteenth century, European booksellers and publishers, mostly from France, England, Germany and Spain, produced textual materials in Europe and introduced them into Mexico and other Latin American countries. These transatlantic interchanges unfolded against the backdrop of the emergence of the international legal system to protect translation rights and required the involvement of a complex network of agents who carried with them publishing, translating and negotiating practices, in addition to books, pamphlets, prints and other goods. Tracing the trajectories of translated books and the socio-cultural, economic and legal forces shaping them, this article examines the legal battle over the translation and publishing rights of Les Leçons de chimie élémentaire, a chemistry book authored by Jean Girardin and translated and published in Spanish by Jean-Frédéric Rosa. Drawing on a socio-historical approach to translation, I argue that the arguments presented by both parties are indicative of the uncertainty surrounding the legal status of translated texts and of the different values then attributed to translation.
