Prof. Spode thanks Burkhard Herbote for the generous donation of 120 folders, sorted by countries, containing information about travel, tourism and geography. This private "Herbote Archive" was built up with an immense amount of labour, time and money. It originally consisted of 350 folders and 1,200 books. Large parts of these materials are now available at the HAT."
