If you're interested in a particular country, world area, or type of music, a subject search in the library catalog filtered to only find library items can be powerful, like the following sample searches:
This search will only turn up books, recordings, or periodicals that are all or mostly about the subject in question. If your searches here don't turn up many relevant hits, consider using a Keyword search instead.
