I was also unable to reach the url that Denise gave directly -- I think a lot
of crummy search programs can't manage URL's that don't start with "www."

However, I was able to reach it be going to
<< www.nih.gov>>

When  you get there click on Search, which is near the top of the home page,
and when the search page comes up search <<mammary AND Hartmann>>.

Hope this helps--
