Are there any other historical sources on Denmark–Norway aside from Wikipedia?

by KinoBlitz

I'm trying to gather more research and sources on the history of Denmark-Norway (their military, culture/reforms, government, notable figures, colonies, etc.), specifically from around the late 1700s/early 1800s. However, I can't find many other reliable sites (that aren't Wikipedia) on Denmark-Norway that go in-depth about its history, aside from vague articles about their union. If anyone can provide some sources I'd really appreciate it!

In Danish, Danmarkshistrorien.dk (provided by Aarhus University) offers decent online resource on Dano-Norwegian union: https://danmarkshistorien.dk/

As for the Norwegian society in the 18th century, a few thematic exhibition by Norwegian folkmuseum like Setesdal 1739 might also be interesting. In Nordic (Scandinavian) countries, many (open air) folk(e)museum features the countryside as well as city life with reconstructed buildings from the 18th century onward (with the interiors).
