INVESTIGATE THE FOOTNOTES AND BIBLIOGRAPHIES OF EVERY GOOD SOURCE, TO FIND LEADS TO MORE SOURCES
EVALUATE SOURCES YOU HAVE FOUND. Where is the information coming from; is it biased or opinionated; is it scholarly; is it up-to-date; can you retrace where the author found the informaiton? Are you using primary source material (e.g. videos, music, interviews with the musician, photographs, reviews of music recordings, live shows, etc. in newspapers, blogs, zines).
