NB615 .P6313 1996. Another is Michelangelo: Sculpture and the call number is NB623.B9 P283. These are on the 2nd floor of the Library.
There is also an article in ArtNews titled, How Michelangelo Made David into a Giant ARTnews; Apr2014, Vol. 113 Issue 4, p52-54, 3p This is available in print from the Reserve desk.
Good luck!
