A selected list. This is not comprehensive, as you can find music information many places. Think first about what subject you might relate your search to, and go looking for databases on that subject. This is a place to start.
These are the instrument-specific journals the music library subscribes to, as well as information on how well they are indexed in the music databases. Some music journals are not indexed anywhere, unfortunately, and have to be flipped through.
