Some of the links, especially to the engravings, are not broken because the I own the original sources and the books are no longer protected by copyright.
In some cases I have been unsuccessful in tracing the ownership or owners of illustrations. If anyone feels that I am in violation of copyright, please notify me immediately so I can make arrangements for permission to reproduce the image.
