Because of the move to online instruction, there are several places you can go to find scores by composers who are people of color or from non-western traditions.
While there are anthologies of composers by various ethnicities and genders, most of the scores in the Performing Arts Collection are organized by genre, and then by composer. Composers of all kinds are mixed in together (though they are dominated by dead white men [thanks musical canon! {eye roll}]), and subject headings generally do not list any demographic information about the composer. In that case, it is best to start with someone that you are searching for. Suggested lists can be found at the bottom of this page.
In Library Search (primo.rowan.edu), there are options to limit your search by format, either before or after searching. This will weed out all of the books, recordings, articles, and reference entries about your composer or piece.
You can use limiters on the side of the search results (here I just searched for "Amy Beach"):
Or you can start in the advanced search, by limiting to scores only:
You can also use the search box below:
Every score in the PAC will be assigned a call number, which functions like an address for finding it on the shelf. At Campbell Library, and at most university libraries, we use the Library of Congress Classification System. It can be tough to understand these numbers, but here is a helpful website that gives you a brief overview: https://www.usg.edu/galileo/skills/unit03/libraries03_04.phtml
The call number can be found in each record for a physical item in Library Search, either in the brief record displayed while searching:
Or twice in the full record:
Call numbers are "read" left to right on each individual shelf in a unit. The shelves are read top to bottom. When you have reached the bottom, then you move to the right to the next unit. A collection of units is called a "range," and there are helpful guides to tell you which call numbers can be found in each range. For example, this Amy Beach score would be found in the range below, because M 512 falls between M 219 and M 557 (and it's a quintet!)
