“Ordinarily the word ‘document’ denotes a textual record. Increasingly sophisticated attempts to provide access to the rapidly growing quantity of available documents raised questions about which should be considered a ‘document’. The answer is important for any definition of the scope of Information Science. Paul Otlet and others developed a functional view of ‘document’ and discussed whether, for example, sculpture, museum objects, and live animals, could be considered ‘documents’. (…) New digital technology renews old questions and also old confusions between medium, message, and meaning.” (Michael K. Buckland)
