Searching the Library Catalog:
When searching for different types of music materials, you can use the "Tweak your Results" function on the right side of the catalog results screen. This is especially helpful when searching for music scores or music recordings.
In the example below, the search for keywords "Beethoven Symphony No. 3" returns over 200 results. Beneath that screenshot you'll see the "resource type" limiter showing that over 90 are recordings and 17 are scores.
