The library subscribes to or has built a number of image databases that are excellent sources of images you can download and add to your papers and other projects. You need to keep in mind that some of them have licensing restricts that prohibit the re-publication (including open web publishing, such as on a blog or on social networking sites) of images you download. There are also quite a few digital collections that are free and open on the web. Use the library Visual Resources page for links and information about how best to use ARTstor and other image databases.
