The Christmas present of the Manuscript Collection of the National and University Library of Iceland to the nation is an electronic catalogue of the manuscripts the Manuscript Collection received in 1964–2013. The catalogue has descriptions of 725 manuscripts and can be found here https://landsbokasafn.is/index.php/efni/handrit/handritaskrar. The manuscripts have also been catalogued on www.handrit.is.
There is still a fair way to go before all the manuscripts received in this period are fully catalogued, and a new edition will be published when 1,000 manuscripts have been catalogued. This is a provisional edition: the descriptions of the manuscripts will later be fuller, and work will be done to make them consistent.
