The Music Library has a vast collection of sound recordings in traditional and online formats. Our CDs and vinyl records do not have Library of Congress call numbers that classify them, so browsing is not helpful. They have numbers we created locally. The next CD or LP gets the next number, beginning with LPCD for CDs or LPZ for records.
Thus, search our online catalog to find specific organ recordings you want:
