Instead he took work as a librarian, first at the Museum of Decorative Arts and Design from 1909 to 1918, then in the Norwegian Parliament from 1921 to his death.
[1] Krogvig also worked in the publishing house Aschehoug, together with Gerhard Gran and director William Martin Nygaard.
He was involved in several of their flagships; being subeditor of the periodical Samtiden from 1916, editor-in-chief of the encyclopedia Achehougs konversasjonsleksikon from 1919, and co-editor of the biographical dictionary Norsk biografisk leksikon from 1921.
Two collections of his articles were published, titled Nordisk digtning (1912) and Bøker og mennesker (1919).
Together with his position in Aschehoug, this meant that Krogvig had a significant impact on many literary careers of the time, including Johan Falkberget, Olav Aukrust, Kristofer Uppdal, and Sigurd Christiansen.
