The map search on Kartenportal.CH: the best place to start your search. Using modern search tools, you can seek information on half a million maps in Switzerland’s libraries and archives quickly and easily. If you know the title and author of the map, the textual search in the online metacatalogue swissbib will prove fruitful. For more difficult searches, specialist staff will support you by email or on site. If you need help with time-consuming searches, however, an appointment is necessary. The contact and access information for online library and archive catalogues is provided here.
