Textual linguistics has been undergoing a continuous redefining of its internal and external boundaries after Halliday & Hasan’s inaugural thesis. It notably concerns the concepts of text and discourse, and has led to the constitution of a new research field: Textual Discourse Analysis (TDA). This paper starts from two questions: “What is a text – or the text – in the digital age?” and “Which new methods are available for textual analysis?” It is assumed that text is neither merely nor principally a linguistic object, but is at the meeting point of various fields and key-concepts: sentence, utterance, document, archive, basis and corpuses, discourse. Answers must be searched in digital philology as well as in the hermeneutic aspects of discourse analysis.
