Except where we have specified otherwise, the wonderful images we have used on this website are from the Flickr Commons project. This project includes photographs from a range of institutions which have no known copyright restrictions and are therefore virtually in the public domain.

This photo, for example, is of Henry Fitch Taylor and was contributed by the Smithsonian Institution.

Another wonderful source of open content is Wikimedia Commons which hosts a variety of multimedia licensed under open licenses such as Creative Commons licenses which permit reuse and facilitate more open sharing online.
