The aim of this paper is to present a collection of documents from the Bibliothèque Cantonale et
Universitaire de Lausanne that has remained intact until now. This collection of Spanish texts was left as a legacy in
1997 by Carlos of Goyeneche and Silvela, Marquis of Balbueno. It is composed of a series of manuscripts that date from
between the XVth and XXth centuries.
Firstly, we will present a first cataloging of every document that the collection is composed of, highlighting some of the
more significant pieces that have been found up until now. Secondly, we will present our research project, explaining
briefly the criteria that we will follow in the transcription of the documents. At the end we will include a section
exploring the possibilities that these documents may contain for research in historical linguistics.
