The general collections of the Music Division contain published and unpublished musical scores, as well as music-related books and periodicals. The Library of Congress Classification System uses letters and numbers to organize individual collection items so that they are shelved with similar materials in our stacks. Items in the Music Division's general collections carry call numbers as outlined in the Class M schedule, broadly organized into three subcategories:
M — music scores
ML — literature about music
MT — works on musical instruction and study

Keep in mind that the Library's Music Division holds over 25 million items in its collections, and only a portion of these materials are individually cataloged; all of our collections, however, are organized, classed, and searchable by on-site librarians. If you have trouble finding a specific score in our online catalog, contact our reference librarians via our Ask A Librarian email reference service for assistance.
