Bibliographies save you time!
A bibliography lists sources on your topic, and sometimes there are annotations that help you better understand what a source is about.
Print bibliographies are in the Reference section of the Music Library.
To see if there is a bibliography on your topic, try searching IUCAT by adding keywords such as:
For example, a search for "guide research mozart" might lead you to a bio-bibliography about Mozart.
Try visiting the guide You Already Have the Citation, which gives you tips on how to find a source when you have a citation from a bibliography.
