The Biographical Materials series contains general records on Delanghe's career and educational background. These include her undergraduate and graduate diplomas, as well as resumes and her master's thesis A Choreography: Odyssey II.
The documentation of Delanghe's choreographic process is contained in the Choreography series. The bulk of this series consists of loose-leaf notes Delanghe produced in conjunction with her pieces. While the sets of notes are often titled, or have been given a title based on the title of their original folder, these may not be the official titles used later in performances. Folders are arranged alphabetically by title or working title. In some cases, these folders contain external materials Delanghe consulted while choreographing her dances. The series also contains notes on contemporary composers and musical genres.
