Resumen:
This paper aims at presenting the Project of Corpus Linguistics in Spanish developed by the research group TesUN of the Universidad de Navarra, which also is a part of the Red CHARTA. The corpus consists of personal ancient documents which date back to 17th, 18th and 19th centuries. These texts were preserved in private archives at private homes in Navarra (Spain). The established corpus is characterized by the heterogeneity of its textual typology, which ranges from notarial documents -copies, testaments, marriage contracts- to private writing -letters, receipts, bills or obituaries-, or, in the case of the former parsonages, sermons and biblical exegesis, as well as letters. Therefore, this corpus opens a wide range of study to paleographers, historians -in particular to those interested in the history of private life and the history of mentalities-, linguists or ethnographers and ethnologists
