Use the library catalog to search for musical scores.
Use the Library Catalog to find items physically located in the library, with the exception of electronic books which you can link out to from within the catalog. Note, you can't use the Library Catalog to find journal articles.
WorldCat is another good source for finding scores, in libraries worldwide. UAF students and faculty may borrow these on Interlibrary Loan, if not owned by Rasmuson Library.
