SOUND RECORDINGS It is possible to see Music Library holdings, including CDs and LPs, online. All sound recordings acquired since 1978 are entered on Barton. If you are looking for CD's, the paper listing available in the Music Library is also available on TechInfo. Remember that it's a "main entry" listing -- this means that access is usually by composer, so if you're looking for a particular performer or a specific musical selection, this won't work. CDs may be borrowed for one day.
