The literature in the first years after the Second World War was characterized by a long series of documentary reports from people who had been in German custody, or who had participated in the resistance efforts during the occupation. The most famous among these were Lise Børsums's "Fange i Ravensbrück", Odd Nansen's "Fra dag til dag" (From Day to Day) and the posthumously published "Petter Moens dagbok" (Petter Moen's diary). Some years later, biographies of heroes of resistance, such as Fridtjof Sælen's "Shetlands-Larsen", about Leif Andreas Larsen, and David Armin Howarth's "Ni liv. Historien om Jan Baalsrud" (Nine Lives – the story of Jan Baalsrud), became major publishing successes.
