The Historical Music Recordings Collection is the major repository at the university for sound recordings and is one of the largest such collections in the United States, housing more than three hundred thousand items and providing examples of a wide variety of genres in almost every type of format. With a dedicated rerecording studio in-house, the collection can also produce high-quality reproductions of materials from the collection for public use and preservation copies of fragile or deteriorating media.
Classical music is predominant among the holdings, but there are considerable collections of original cast recordings of movie musicals and Broadway shows, early jazz and blues, and pop and rock music from the 1950s through the 1980s. The Historical Music Recordings Collection also maintains tapes of radio broadcasts, including nationally syndicated dramatic productions, and serves as the public repository for recordings of the Austin and Houston Symphony Orchestras and has a large collection of piano rolls.
