This demo presentation will offer an interactive demonstration of the website ‘Lexicon of Scholarly Editing’ (www.uantwerpen.be/lexicon-scholarly-editing), a digital resource that collects definitions of important concepts in the field of Textual Criti- cism. Based on the WordPress infrastructure, the author built the Lexicon as part of his work on the ‘Creative Undoing and Textual Scholarship (CUTS)’ project, funded by the ERC and supervised by Dirk Van Hulle. The project is affiliated to the Centre for Manuscript Genetics (CMG) at the University of Antwerp, and the European Society for Textual Scholarship (ESTS).
