In the case of dance, opera, and other staged works, music is only one of many elements that contribute to the final product. Primary source materials such as notes on choreography, costume and set design sketches, photographs, video footage of rehearsals, and stage directions are elements that should be considered when doing research on such works. Music also plays a role in a larger cultural context, and interdisciplinary research is of increasing importance.
Blue Mountain Project: Historic Avant-Garde Periodicals for Digital Research - A digital project initiated by Princeton University with support from the National Endowment for the Humanities, the Blue Mountain Project concentrates on "the scarce and ephemeral texts of the period between 1848 and 1923: journals, magazines, manifestos, and other publications which, taken together, underlay the emergence of modernity in Europe and the Americas." The project creates machine-readable transcriptions of the texts, and all metadata associated with the project is freely available in its GitHub Repository. At this time, Blue Mountain has 35 titles available, including Action, Dada, Der Sturm, East & West, La Revue musicale, and Secession.
