In this essay, we would like to underline the relevance of international digital media as a corpus of research that contributes to our understanding of the history of the Spanish lexicon. We present tools such as corpora and word banks, especially elaborated for the Hispanic tradition. For example, we would like to examine some research projects in Romance or Hispanic linguistics that are in the Anglo-Saxon, French or German university networks or accessible in online libraries. Particularly, in this essay, we present some cases where research in historical lexicology was complemented with data provided by the whole digital ecosystem. For this research, we will only focus on two areas of Hispanic lexicology: that of Romance etymology and that of the history of the Spanish-American lexicon.
