In Pamplona circulated, as in the rest of the Hispanic Monarchy, the news pamphlets, so the Kingdom of Navarre was not excluded from this publishing business. Obvious evidence of this phenomenon will be the testimonies from the workshop of Martín de Labayen, who promprly published different news pamphlets between 1636 and 1648. But this work not muy addresses its production or its figure as editor, but also we will immerse ourselves in other aspects of his life as a printer thanks to the archived documents rescued.
