Since a few years we know of the De Geer Archive, a collection of glass negatives of Spitsbergen, relating to De Geer's expeditions between 1882 and 1910. The negatives have only emerged recently and a collection of prints relating to Holmströmbreen and Sefströmbreen is included here. Together with a third paper incorporated in the book, this time an evaluation of De Geer's photos and maps of the Sefströmbreen surge, this material shows the importance of incorporating historical documentation in our studies.
