The first volume includes the introductory texts and a chronological essay on the artist's life. The appendix contains excerpts from contemporary reviews of Dahl's art. There are also excerpts from Dahl's autographical notes, correspondence, and statements on art and nature. There are also texts relating to the artist's relationship with Prince Christian Frederik, as well as the itineraries of Dahl's Norwegian journeys. The second volume has a survey of sources, exhibitions, and cites problems of attribution. This is followed by a chronological catalogue raisonné of 1300 works, (with thorough critical apparatus), supplemented by works that are undated and a list of doubtful attributions. There are indices by subject and proper names, and a list of the present locations of the works.
