Archivo de la web española
The Spanish Web Archive is the collection formed by the websites (including blogs, forums, documents, images, videos, etc.) that are collected in order to preserve the Spanish documentary heritage on the Internet and ensure access to it.
Due to the enormous size of the Internet and the technological means currently available, it is currently impossible to aspire to exhaustiveness in web archiving. Therefore, in order to try to store as much web information as possible, the Biblioteca Nacional de España has opted for a mixed model that combines massive and selective collections, as other national libraries around the world do.
