Grundtvig had amalgamated what he considered useful features from various versions of a folksong or ballad to produce a long, complex whole; Olrik, in contrast, sought to trace the history of the oral texts back to simple originals. He published several sample studies in Danske Studier, the journal he co-founded with Marius Kristensen in 1904, and in 1899–1909, with Ida Falbe-Hansen, he published a collection of reconstructed texts, Danske Folkeviser i Udvalg (Selection of Danish Folk Songs); in 1899–1904, an edition with melodic arrangements by Thomas Laub was published. These were very popular and were translated into German and English.
