Author / Author-Title
If you are citing a work multiple times, include the full citation only the first time. Subsequent citations include only the (1) last name of author and page number, or (2) last name of author, shortened title, and page number. Make sure to check with your professor to see which style they prefer. The second method has the advantage of reminding the reader of the title of the work, and is essential if you are citing more than one work by the same author or composer. The shortened title is composed of up to four distinctive words from the full title.
