The Atlas Working Group (AWG) acts as the scientific platform for the European Historic Towns Atlas project, the main project of the International Commission for the History of Towns since 1968. Whereas until 1989/90 the United Kingdom, Germany, Finland, Austria, France, The Netherlands, Denmark, Sweden, Ireland, Italy, Iceland and Belgium had joined the project, after the great political changes of 1989/90 the number of national historic town atlases increased a lot: Poland (1993), the Czech Republic (1995), Switzerland (1997), Romania (2000), Croatia (2003), Hungary (2010), and the Ukraine (2014). In order to support this progress the late President of the International Commission for the History of Towns Adriaan Verhulst (Belgium) initiated the AWG in 1993. Anngret Simms (Ireland) and Ferdinand Opll (Austria) were the first conveners later joined by Katalin Szende (Budapest) and Keith Lilley (Belfast). Membership of the AWG was extended to colleagues who were not elected representatives of their countries on the Commission but were actively involved in producing national historic town atlases according to the guidelines of the Commission.The AWG acts as the scientific platform for the European Historic Towns Atlas project by encouraging conferences and workshops on special issues as for example a common methodology in map production, comparative urban studies or the digitisation of the town atlases. The long list of such meetings includes Münster 1995, Bologna 1997, Bordeaux 1999, Dublin 2006, Münster 2007, Dublin 2015, 2016, 2017, 2018, Cracow 2017, Salzburg 2018.  References
