Thank you for your reply. If I understand correctly, the options you are talking about can be reached through the desktop application, under Tools > Clipping Preferences. There is a check box that says "Do not show the "New Clip" dialog. I have the box unchecked, so I always see the Related Results page after clipping. The feature I am interested would let me know in advance of clipping a page whether it was already clipped. I want to avoid taking the time to clip a page that has already been clipped.
