Some very useful video tutorials on using CLIO beta have been put up by Barnard Library, at this link. Although the videos emphasize Barnard content, they are still an excellent introduction to some of the general features of CLIO beta, and to searching in general.
For searching CLIO for music-related items, one additional thing to note is that you can limit your title or keyword searches to music sound recordings, music scores, or videorecordings, by using the “Limit To” drop-down menu, below the search box.
If you find that you have additional questions about searching for recordings or for music scores, don’t hesitate to contact us, at musiclibrary@columbia.edu!
