Writing up your family history can be enhanced by pictures and maps.
Too often they are copyright or watermarked. That's fine, but so many pictures from old books are out of copyright.
It was wonderful that one of my links sent me the details of the 'Digital Library of America', I'm now enjoying the search for new pictures and maps that can illustrate my family history.
I've even discovered Sergeant Wayne A Cuffley, a very distant relative, has provided photographs to the USAF and these are available on the site.
Its amazing how the availability of knowledge has increased over the last ten years.
