ISO/TR 14873:2013 defines statistics, terms and quality criteria for Web archiving. It considers the needs and practices across a wide range of organisations such as libraries, archives, museums, research centres and heritage foundations. ISO/TR 14873:2013 is intended for professionals directly involved in Web archiving. It is also useful for Web archiving institutions' funding authorities and external stakeholders. The terminology used in ISO/TR 14873:2013 attempts to reflect the wide range of interests and expertise of the audiences, striking a balance between computer science, management and librarianship. ISO/TR 14873:2013 essentially focuses on Web archiving principles and methods and does not encompass alternative ways of collecting Internet resources.
