This New York Public Library collection of Italian dance materials covers the Renaissance to the early 20th century, assembled by none other than the son of the famed conductor Arturo Toscanini and his wife, a La Scala ballerina. Although the physical collection contains over 3,300 items, the number of digitized items is 373, which is still quite impressive. Visitors can click on "Collection Contents" to the right of the Niccolo Sanesi image on the homepage to see that the subject matter is broken down into "Ballets and theatrical dances", "Subjects", and "Portraits", and can be browsed via those broad categories. Alternatively, users can click on "See all images", on the homepage near the top of the page, and simply browse the collection of designs, lithographs, ephemera, and more. Visitors can click on "Add to Selections" below any image to purchase a print of the image or to start a request for editorial/creative use. The "My Selections" link at the very top of the page lets the visitor see what they have put in there, and remove it, if need be.
