ENREDOS BIBLIOGRÁFICOS Y CATALOGACIÓN: PEDRO ESCUER Y SUS SUPUESTAS EMISIONES DE 1634.

It is intended to show how necessary the Bibliography is to carry out a correct cataloging of the old book. To do this, three works by Prudencio de Sandoval are studied that were published in Pamplona between 1614 and 1615, and subsequently all of them supposedly republished in the form of broadcasts by Pedro Escuer in 1634. Thanks to this work, it is verified that after these last ones there was also Martín de Labayen, a printer from Pamplona who would have agreed with the merchant from Zaragoza to put these titles on the market as if they were new editions. It is possible to clarify, therefore, this bibliographic entanglement. [ABSTRACT FROM AUTHOR]
