3. ELAG 2004Workshop 5 report3 Workshop Charge This workshop uses the term ‘access control’ as it has been used by Barbara Tillett1. This means, not just the traditional authority control of names, but adding the possibilities for more localization so that a reader can search and see names in the form they are most used to. The workshop is not about controlling access to online resources via user authentication. 1 Tillett, Barbara B. International shared resource records for controlled access.
