The M schedule of the Library of Congress Classification scheme is where you can find music scores and sound recordings. When browsing our online catalog or browsing the shelves in the library, use these posters (created by Bowling Green State University) to help you zero in on the music you want. For example, search M268 and/or M269 to look for solo saxophone music. To browse the online catalog, select the Browse Search option in the upper right of the interface. Additional posters are shown below to help with ML and MT classification, too.
