Sibley Music Library's score and book collections are organized according to the Library of Congress Music Classification System. This library guide will provide a general outline of the M, ML, and MT schemes (along with the classifications of non-music items in the library). In addition, it will guide you to the specific locations where these classed materials are shelved.
The three LC Music classifications are:
M: music scores
ML: literature on music
MT: musical instruction and study (scores or books)
In addition, Sibley holds a small but significant collection of items that have Classification letters not beginning with M.
