Use the Library Catalog to find what books, CDs, LPs, etc. on your topic. Keywords work well - make sure you note synonyms of your key concepts and search using them also:
ex.: "rock music" "rock and roll" "rock n roll" "country rock" "twist music" "twist dance" "teenagers" "rock music social aspects"
TIP: the abstracts and subject headings in the full record for an item, may lead you to other keywords. You may notice that similar call numbers are assigned to books with similar topics. When you go to look for a specific book, be sure to look at the others on the shelf around, it they might work even better for your project!
