Sometimes you know exactly what piece you are looking for. Suppose you want a score of Elliott Carter's Eight Pieces for Four Timpani. Go to the Libraries' home page at http://www.lib.ua.edu. Click on "Libraries Catalog" on the home page; then click on Advanced Search. In the first box, type in the composer's name, last name first: "carter, elliott," and choose "as a phrase" and "author" from the drop-down menus at the right. In the second box type "eight pieces" (no need to capitalize names or titles), and choose "as a phrase" and "title" in the drop-down menus. In the drop-down menu next to Type, choose "music score." Then click Search. You will find the catalog record of the score with the call number.
