There are two internet resources that have recently launched that you may find interesting. The first is Mediterranean Memory (Mem-Med), an online audiovisual library and archive focusing on the Mediterranean area. Currently there are 4,000 audiovisual items in French, English, and Arabic, as well as some articles. A “how-to” guide is here.
The Rijksmuseum in Amsterdam has placed 125,000 items from their collection online in what they are calling Rijks Studio. Found a painting that might work for your project? You can zoom in, crop, download, and even print these hi-res images. Have fun exploring a museum that is currently closed for renovations until April 2013.
