Music Index indexes international journals, dissertations and topics in music. Many students find it easier to use than RILM Abstracts because there is less international coverage. You can limit at the first search screen or at the results screen. Let's start with a search for Puccini and women.
Here's a results screen for a search on Puccini and women. While skimming 30 entries isn't terrible, let's look at the options to refine or limit the search circled in red. Show more will provide more options.
Let's try refining the search to scholarly (peer reviewed) journals and see what happens.
Now you have a smaller result set to review. You can also add words such as titles of roles or terms to further narrow your search.
Be sure to use the Find it @ FSU link to see if the item is available online. Sometimes you may need to copy and paste the journal or book title and try searching in the library catalog if your search for the online version is not successful.
