The Library of Congress classification system for music is divided into three broad areas:
M = Musical scores and audio and video recordings of actual performances of music. Most of the library's CD collection and many videos are shelved in the Ms.
ML = Literature about music. Biographies, histories, documentaries, and some historically-based CD anthologies are shelved in the MLs.
MT = Materials for the teaching and study of music. Some historical or practical materials with a strong analytical or didactic bent are also shelved in the MTs.
Books and recordings on jazz are scattered throughout the collection, but there are several areas of concentration that lend themselves to browsing:
M 1366 contains most jazz recordings and transcriptions
M 1503-1507 include lighter forms of dramatic music, including operetta, musicals, and anthologies of excerpts from musical theater
M 1629-1630s contain popular songs
ML 417-419 contains many biographies of jazz musicians
ML 3534 contains many books about the history of Rock.
ML 1711.8, 2054, 2075 have concentrations of books about Broadway and Hollywood musicals and songs
ML 3506-3518 history of jazz
