The Music Resource Center (MRC) is a branch of CMU's Park Library and is located on the ground floor of the Music Building in room 132. It is comprised of a collection of over 15,000 phonograph records, compact discs, and tapes, as well as a selection of CD-ROMs, printed study scores, and music reference books. In addition to these resources, the MRC houses audio and video equipment for in-house listening and viewing of materials. The Computer Aided Music Instruction Lab (CAMIL), which contains computers and various software products, is also located within the MRC and is for music major use. The main area of the MRC also has computers with Internet access and various work processing/data management software.

Although the Music Resource Center is primarily used by faculty, staff, and students of the School of Music, all members of the CMU community and guests who hold current CMU Library borrowing privileges are welcome to use the MRC and its materials.
