Most professors of art history require that you use of the Chicago citation style to create bibliographies and footnotes. There is also a variant of Chicago known as the Turabian citation style that is used as well. Because citations direct your reader back to the work of scholarship you are using in your research, they will differ slightly depending on the type of research material you are working with. For example, an article in a book will include information about the publisher of the book, while an article in a journal will include the name of the journal and its volume and issue number. It is best to include as much information about the resources you are working with as possible so anyone who wishes to look at those resources will be able to find them.
Image captions should include both the location of the work of art itself, as well as the location of where you found the image. Below is an example of an image from the Metropolitan Museum of Art's collection and how you would cite it depending on where you found the image
