La trayectoria de los materiales inicialmente destinados al Glosario de 'Orígenes del español'

Ramon Menendez Pidal originally planned Origenes del espanol with a glossary that was intended to be a second part of it, the Glosario del espanol primitivo. This task was given to the young Rafael Lapesa, but the material and data collected suffered some vicissitudes before and after the Spanish Civil War. After the death of Lapesa, Manuel Seco assumed and conducted the preparations in order to publish the materials that were given and donated long ago to the RAE - donation pursued to help the preparation and creation of the Diccionario historico in the late 70s. From this given documentation was published a book known as Lexico hispanico primitivo. In the present study we analyse and contrast the different periods of elaboration suffered by those materials. Moreover, we note that the work initially planned as a glossary of old Castilian evolved to a Glosario iberorromanico, with a fully Hispanic amplitude, all of it still partially unpublished.
