Amongst the millions of scores held by the Performing Arts Reading Room at the Library of Congress, hundreds, if not thousands, originate from Denmark, or are in the Danish language. (The latter include some scores that were published in the United States). Please keep in mind that many of the scores in the custody of the Performing Arts Reading Room are not found in the online catalog, but in the physical card catalog. Especially in the case of sheet music, some scores are not even recorded in the card catalog. Instead, this sheet music is filed under genre or topic, and then by composer last name. If you are looking for a particular score and cannot find it in the online catalog, please ask a Performing Arts reference librarian.

The holdings of the Performing Arts Reading Room contain over 400 monographs and collections of secondary literature on the subject of Danish music, as well as about two dozen periodicals on the same. In addition, the collection includes hundreds more monographs on specific Danish composers and musicians.

The Performing Arts Reading Room is also home to the Albert Schatz Collection, which consists of over 12,000 libretti. These include a first edition of Liden Kirsten [Little Kirsten], a one-act opera for which Hans Christian Andersen wrote the libretto, and Johan Peter Emilius Hartmann the score; as well as a first edition of Et Eventyr i Rosenborg Have [An adventure in Rosenborg Gardens], a one act “operette,” the supposed librettist of which was Johan Ludvig Heiberg, and the supposed composer Christoph Ernst Friedrich Weyse. The Schatz Collection contains well over one hundred Danish-language libretti, many of them authored by poetic greats like Johan Wessel, Johannes Ewald, Jens Baggesen, and Adam Oehlenschläger.
