The basic information you will need:
• Artist’s name
• Title of the work
• Date it was created
• Repository, museum, or owner (in other words, where it is now located)
• City or country of origin
• Dimensions of the work
• Material or medium (oil on canvas, marble, found objects, etc.)
• Image Source
If you found the image in a book, you will also need the author, title, publisher information, date, page, and figure or plate number of the reproduction. If you found the image online, you will need an access date, the web site address (URL), and, in some cases, an image ID number.
