Among them, Rosa Fernández Lera (Director of Biblioteca de Menéndez Pelayo, Santander, Spain), M.ª del Carmen Roig Santos (Biblioteca Histórica “Marqués de Valdecilla”, Madrid), Dr. Marieke van Delft (Curator of Early Printed Editions, Koninklijke Bibliotheek, National Library of the Netherlands, The Hague), Helena Patrício (National Library of Portugal), Domniki Papadimitriouki (Cambridge University Library), Chris Rawlings and Sandra Powlette (The British Library), and the personnel at the Biblioteca Nacional de España, the Archivo Diocesano de Gerona, and the Biblioteca Regional de Madrid. I owe a special acknowledgement to Marcella Mulder for her help and advice throughout the publishing process, to Sam McCracken for having dared to translate many very crucial pages, and to Matthew Roudané for thoroughly reading this manuscript. Amongst all to my mom, for bringing home El Caso, “the portresses’ newspaper”, and gutting it with me.
