Their library is a member of the national library association who recently received state funding to make available online the resources held by its members. The NHM-DK would like to begin digitization of the field notebooks, journal publications and books held in their library, some of which have significant historic value. After a short consultation with their regular partners, NHM-DK received a suggestion from the Head of the management office of the Nordjylland National Park. They would like the contents of a particular classic literature compilation digitized for a project they are running: ‘Birds at the Danish Lighthouses, 1883–1939’ (In Danish, ‘Fuglene ved de danske Fyr, 1883–1939’). They want to use any occurrence data recorded in those books from two lighthouses (Lodbjerg Fyr and Hanstholm Fyr) for an on-site exhibition project. The NHM-DK has started discussions with their national GBIF node, DanBIF, about the mobilization of the information contained in these volumes, namely to preserve their contents for the future and provide online access for everyone.

Lighthouse keepers originally recorded bird observations and weather conditions opportunistically during migration seasons (1883–1939), preserving specimens for museum cataloging. The sampling area in this study encompassed 45 Danish lighthouses and lightships, with observations recorded opportunistically by lighthouse keepers during nocturnal bird migration events between 1883 and 1939 Observations recorded by lighthouse keepers at 45 Danish lighthouses and lightships between 1883 and 1939 Valentina Antolinez 2025-05-19T20:19:29.757+00:00 dataset Antolinez V (2025).
