摘要：Starting from the consideration of the document from a structural point of view, as support carrier of a message, we explain the diverse approaches to systematize the document, particularly considering the documentary classifications regarding the support carrier and the message transmission media. We conclude there is a need to revise these classifications due to the introduction of the digital document in the informative scene. The main opposition at present is not that between book and non-book materials, textual or non- textual documents, but that between analogic and digital documents. The differences between the latter are studied, and finally a new typology and classification are proposed.
