RILM is the main database for music research, but we have several more that apply.
Our music research databases index many articles to which we don't have immediate full text access. Sign up for an interlibrary loan account (free) as soon as possible so you can order any articles that we don't have in full text.
All issues in the stacks; no issues past 2015.
OR try Google Scholar. Google Scholar is a useful resource because on campus it will link to full text in any of our databases--make sure to use Advanced Search (you have to click on the "More" down arrow).
Anything we don't have, simply request from Interlibrary Loan!
