EWGLA was born during the first EURO Summer Institute, held at Brussels, July/August 1984, devoted to the subject of Location Theory. At that time the main aim of starting up the Working Group was to provide a network of people working together and to keep continuity in the exchanges between the Summer Institute’s participants. Since that time the group has known important growth and broadened its scope and purpose. Friendship among its members continues however to play an important role.
