All antique maps of Iceland (older than 1900) that are in the collections of the National and University Library of Iceland and the Central Bank of Iceland have been converted to a digital format and are accessible here. A short historical description in Icelandic and English is available for most of the maps. They are based on the book Kortasaga Íslands (A history of cartography of Iceland) by Haraldur Sigurðsson.
